Photo Blast: Cactus Wren

Posted in Arizona, Bird Banding, Birding, Mexico, Navopatia Field Station, Sonora, Southeastern Arizona, United States on September 19, 2010 by Brendan McGarry

The Cactus Wren is the state bird of Arizona, but that is probably the least interesting of designations.  More importantly it is also a member of one of the largest genera of wrens Campylorhynchus, dominating both in size and number of species (the largest, Giant Wren is a congener).  One can also infer that it is a desert obligate, only living in Northern Mexico and the Southern US.   It by far the largest wren in the United States, by several inches, and also the only representative of the genus here.  They make great stashes of domed nests in Cholla Cactus, are easily spotted on a stroll through the scrub.  Common, inquisitive birds, that spout an iconic wavering, churring call, as the rain has picked up in Seattle I’ve had dreams about them and their domain.

Mexico Part 8 – The End

Posted in Alamos, Birding, Birds, Conservation, Environmentalism, Mexico, Natural History, Sonora with tags , , , , , on April 24, 2010 by Brendan McGarry

Unfortunately for almost everyone else, food poisoning interrupted the group’s fun near the end of the trip. I managed to stay bug free and enjoyed all the food put in front of me. Although it’s easy for me to say, if relatively minor food poisoning (no food poisoning is really that minor in terms of comfort) was the only major issue we had, I think we got off pretty well!

We explored the surrounding region for the next two days and despite some illness, largely had fun. In the town of Aduana, we caught a glimpse of a Ferruginous Pygmy-Owl catch a unfortunate lizard mere feet from us. We watched Happy Wrens gaily flitting among the undergrowth. A return to the river granted us magical views of a young Tiger-heron and a troop of Rufous-belled Chachalacas. A Sinaloan Wren, which I’d only briefly seen before, gave Jeff and I quite a show, casting aside skulkiness to investigate an old becard nest.


Without poeticizing every little moment of the trip, this was a stunning way to begin many future travels to Mexico. We made out way back and crossed back into the United States scot-free. The trip was a success with 200 species of birds, I had 18 life birds.

However, it was strange how quickly we melded back into American culture on crossing an imaginary line. Nothing seemed as colorful, surreal, or interesting. Just chain restaurants and golf courses that shouldn’t exist. When I see and hear about lands and peoples far away, my first impulse is to rush off there. But as I’ve grown older I’ve tried to temper that excitement and make others see these places and care. Because it’s easy to watch Planet Earth on your wide screen TV, while eating a meal of takeout, and pretend to be concerned for the planet.

Wingtrip is a project to make these places real, comprehendible, and interesting. As beautiful as Planet Earth or other documentaries are, I believe they unfortunately represent a fantasy being gobbled up by an entertainment-addicted populace. I love these shows just as much as the rest, they are my fix for extended time in the city. I am in no way advocating their insignificance or suggesting they never inspire people. However I also believe that you need to see the people out there, the reality and interaction of people and place. I want you to know how much fun we’re having exploring and attempting to make a difference in the world. Conservation and Science (not that this trip was for conservation or science) are hard work often-unforgiving paths but the people involved experience so much. To put it poorly, it’s very cool and they deserve to be understood and appreciated.
The human role in the planet is palpable in places like Mexico. They can’t avoid their trash by throwing it in a bin and forgetting it; they have to make choices between living and destroying their environments. They can’t all sit in front of a computer and preach environmentalism while being very much removed  (yes I’m alluding to myself and my compatriots). My hope is that through reading about my friends’ and my travels in Mexico you’ll find yourself interested and possibly visit yourself. Maybe you’ll fall in love with the stark Pitayal or the verdant hills of Alamos and start to care yourself.  It’s easy, it’s cheap, the food is good and the people are amazingly friendly.  I look forward to hearing about your travels there soon.

Mexico Part 7 – Rio Cuchujaqui

Posted in Alamos, Birding, Birds, Mexico, Natural History, Plants, Science, Sonora on April 22, 2010 by Brendan McGarry

The Rio Cuchujaqui’s best birding is accessible through the Mentidero Wash, just outside of Alamos. Even as we started making our way down the wash it was starting to heat up and I was getting the anxious feeling that comes when I feel I’ve missed a good opportunity to see new birds. I was also developing a foul mood because the dogs kept screaming ahead of me, chasing all the birds.
I needn’t have worried. Our specific destination was a group of fig trees abutting a cliff wall about a mile up the river. Simone, Alex, and I were leading because we were frustrated with the dogs and accidentally stumbled on the figs. Almost immediately we found an Elegant Trogon!

As we stood there enjoying several trogons (I got excited and tried to make them the less common Mountain Trogon), Sarah stared fixedly at a spot deep in the fig. In a peculiar voice she said, “I feel like there’s something non-avian in that tree.” Was this some sort of 6th sense for the non-avian?
A second later, we saw movement where she was looking. The first Coati I’ve ever seen popped into view and started a retreat down the tree. Apparently we’d awakened it from a nap with our excited shouting. By the time the rest of the group arrived it had disappeared.
Things began whirl in excitement quickly after everyone showed up. Lifers were popping out of everywhere. A Rufous-bellied Chachalaca, in characteristic clumsiness, crashed out of a tree behind the fig. Rose-throated Becard flitted overhead in the tall Monterrey Bald Cypress. Hummingbirds were all around but one caught my eye, a Plain-capped Starthroat. I finally managed glimpses of a Sinaloan Wren. Not a lifer, but a good bird nonetheless, a Squirrel Cuckoo bounced off in the background. This was the spot!

After running into a colonial spider nest (think spiders in every orifice) while bushwhacking in the Amazon and encounters with Tiger Snakes in Australia, I’ve always been hesitant to dash into brush in exotic places. But ubiquitous birdlife can still overwhelm my prudence. Just as Oliver and I spotted Purplish-backed Jays high on the hillside behind the figs, some of the others had found Elegant Quail at the cliff base. No consideration necessary, into the bushes I dashed.


I didn’t manage to see the quail or a Yellow Grosbeak, which I barely missed getting onto. For people who aren’t birders or unfamiliar with these species, many are endemic to this region of Northwestern Mexico. These were special, special birds, seen nowhere else. However, as we stood admiring the orioles, magpie-jays, and warblers streaming in and out of the fig, we found another gem. A bird visually akin to a Townsend’s Solitaire, sat in view for a few seconds. A Brown-backed Solitaire, far away from the montane locales it was supposed to be!

Eventually the group decided that they wanted to sit by the river and go swimming. Simone and I weren’t done (we’re never really done). As the Common Black- and Gray Hawks soared overhead, we continued down the river for a bizarrely but appropriately name bird, a Bare-throated Tiger Heron.

It was strange seeing Lesser Yellowlegs in this seemingly tropical riverbed. I had to remind myself that we were at the intersection of North and South. From here the gray-green Tropical Deciduous Forest (which would harbor many more new species in breeding season) stretched south to Costa Rica. But high in the mountains were the Ponderosa Pine and Douglas Fir of back home. When enjoying nature, there’s nothing better at making you feel insignificant than contemplating biogeography.


We managed some fleeting views of the Tiger-heron, however they were being very skittish. As we started back we encountered a group of Mexican men walking the riverbed with guns and fishing poles (a possible reason for the herons being skittish). Seeing as there were seven of them and two of us, I was a bit nervous but it turned out they were only fishing and very friendly. They asked us if we’d seen any fish. “Solamente pajaros!” I dislike revealing insecurities that could be perceived as prejudice, but things can happen when you are alone with strangers in a remote places anywhere in the world and boys with guns are prone to taking the occasional shot at a living target.


Back at the Pedregal we picked up another new bird that Oli had mentioned he’d seen the day before. A Blue-hooded Euphonia, soon to be renamed Elegant Euphonia and gain status of endemism to Northwestern Mexico. A surreal blue and orange male sat high in a tree outside the straw bale emphatically spouting a vaguely Pine Sisikin-like array. It was a great end to a exciting day of birds.

Mexico Part 6 – Alamos

Posted in Alamos, Birding, Birds, Mexico, Natural History, Plants, Sonora on April 20, 2010 by Brendan McGarry

Heading east from Navajoa, Sonora, you face the prominent Sierra de Alamos, you’ll eventually find yourself in rolling hills. A visibly diverse canopy of a muted green develops and you are no longer in the flat coastal scrublands. Morning Glory trees, with pendulous white flowers appear irregularly along the roadside. You’ll pass through a large gateway, seemingly in the middle of nowhere, and you are in Alamos.

We arrived in Alamos late, missed rendezvous with Oliver and his parents. This got us off to a rocky start. But it was an absolute joy to sit as the town came to life, after the solitude of Navopatia. It took a second for me to relax in a new place without a plan, but everything worked out and we found a place to stay.

Alamos is a town of about 25,000, but when you sit in the main plaza it feels like much less populous. The municipality was founded in the late 17th century in the advent of silver mining in the area. Designed by the King of Spain’s personal architect at the time, it is known as ‘La Ciudad de los Portales” because of its many large doorways and walkways. As we explored the area in the next few days, Alamos’s age was apparent, although in recent years gringos have revamped the dilapidated mansions and tourists have begun to flock, bringing money for modern augments. There was still a large degree of historical charm.


One of the unique things about the town is the high sidewalks: they’re extremely tall, in some places coming up to my stomach (I’m 6’). The purpose is to accommodate for the monsoons that rage through in mid summer. Being in the mountains, they get the full brunt of run off from these storms and they literally flood the streets daily. In the off season, it made avoiding cars on the ubiquitous narrow streets difficult.

We ended up renting an amazing place up the hill from the main town. El Pedregal is run by Jennifer and David Mackay and is set on an amazing swath of undeveloped forest and scrub. Letting us dirt bags stay in their straw bail building was incredibly generous. It meant we got to wake up in a birding paradise, pick Dave’s brain for places to gallivant, and explore the town from a comfortable locale.

My excitement about finally being in Tropical Deciduous Forest was overwhelming and I didn’t get a good night’s sleep as a result. Anticipation of this new habitat was palpable in my peers as well, we were pretty much all up and birding around the property by a chilly, chilly daybreak. Jeff and I almost immediately found Black-throated Magpie-Jays because they flew by screaming their heads off. Though gorgeous birds, they look as if someone put them together fancifully (but masterfully) with feathers and glue. I was excited to put some studying to use and pick out a few white-crested juveniles among the bevy. Violet-crowned Hummingbirds were calling everywhere – a bird that I’d only seen singly in Patagonia, Arizona. They were squeaking their territorial claims throughout the loose sub-tropical forest.

We’d explored the property fairly well, talking to a group from High and Lonesome Bird Tours about the birds they’d seen. We all sat patiently and watched a female Black-vented Oriole peruse a leafless but blooming Tree Morning Glory (Ipomoea arborescens ) along with other Orioles and the never-ending stream of Orange-crowned Warblers. The next day I found a Tropical Parula, a good bird for the region this time of year, enjoying the blooms.

Pulling a large group together, even excited birders, can take time. The time had finally come to head out to the Rio Cuchujaqui, but we had some stragglers (including a poodle and labradoodle whom I was not thrilled were coming along). Thankfully, while milling about waiting for the roundup, a group of Mexican Parrotlets flew in over us and landed right on the property. These sparrow-sized parrots hardly ever land in plain view and we got the best looks we could have hoped for. Chirping and preening, they sat happily in view just long enough for us to round-up everyone and hop in our vehicles.

Mexico Part 5 – Bird Island

Posted in Birding, Birds, Conservation, Mexico, Natural History, Navopatia Field Station, Road Tripping, Science, Sonora on April 14, 2010 by Brendan McGarry


In case it hasn’t been clear just yet, Navopatia is a coastal locale. Let your imagination meander and I imagine you’ll arrive at common local vocation. Fishing.

The fringe benefit for visiting naturalists and birders are the many boats ready for hire. Tino, who lives and works in the village and for the field station is happy to make money off taking visitors out to the aptly named Bird Island. With the going rate at $10/person and a full boat of 10 people, Tino makes a good wage (there’s plenty of people who don’t make that in a day in the US). And for us, ten bon-a-fide greenbacks was a deal to see breeding Blue-footed Boobies!

We’d been trying to make it out to the island before leaving for Alamos. The wind and Tino needing to accommodate other groups hadn’t allowed the venture until now. The morning of the afternoon departure to Alamos, we clambered on and coasted out to the open water.

In the wide channels that feed the estuary, mangroves and all their charismatic inhabitants flanked us as the boat crawled forth. Although my bouts with seasickness have been directly dependent on being in heavy waves and distance from shore, I was willfully avoiding being ill. Thankfully, as we broke into the open water, I had ample distraction.

As many times as I’ve watched boobies and gannets slice into water on film, it has never done them justice. At the risk of making evolution sound sentient, boobies are perfectly engineered for these stoops. Seeing their quarry from high above, boobies plummet and transform to spears thrust from Poseidon. They shed any resemblance to birds the split second before impact.

Blue-footed Boobies in most respects however, aren’t as graceful as they are when foraging. Well built for living at sea, they quickly diminish in elegance right when they try to land. Feet thrust forward and gangly wings stuck at awkward angles, like someone trying to brace their fall, many of the birds seemed elated in the simple miracle of coming to ground without mishap. Beaks clattering, they’d uttering bizarre noises on successful stops.

Bird Island itself isn’t horribly fascinating from a geological perspective – it’s just an eroding bit of sand. Hardly an island at all. But it was full of birds: both species of Pelicans, Brown and Blue-footed Boobies, cormorants, geese, ducks, shorebirds, pretty much every bird in the estuary. Tino brought the boat up close but to be respectful, we didn’t go to land.

Breeding bird colonies are not places of glamour either. Behaviorally, yes – very fascinating. But let’s not ignore that fact that this island was mostly bird shit from obligatory piscivores (we got a full whiff of this one the far side of the island). The excrement of birds that eat fish all day and exude it to bake in the sun, does not remind one of rose petals. Then there’s the noise and the complete lack of shade – you can probably assume I’m not destined to work with Nasca Boobies in the Galapagos.

But you don’t visit these places for the ambiance. You come because you get to see a White Pelican stretch its proboscis skyward, the absurdist yoga. To watch Blue-footed Boobies assume courtship displays, clownishly raising their latex gloved feet up and down in unison. To hear the excited whistling and humming of the birds as they go about lives that don’t include our own. And best of all, to admire the babes.

Baby boobies are the oddest baby birds I’ve ever seen. These fluffy white muppet like birds were few in numbers and easily missed amongst the whitewash, mainly because they were sprawled about like discarded feather boas. They didn’t look comfortable and I was reminded of two days earlier when I’d slept one off. This was probably akin to that, an inescapable, nauseating discomfort. However, I’d had the option of not baking in the sun (and not imbibing so lavishly).

I stared at one for about ten minutes, willing it to move. It didn’t. Even when an adult bird pummeled the ground adjacent during a particularly graceless landing, it stayed motionless. Finally it half-heartedly nibbled at the nearby adult’s chin. Not the penultimate of begging. But I’ll be damned if they weren’t deathly cute. You can take baby penguins, I’ll take these nonchalant albino Elmos over them any day. I’d probably suffer less hangovers if I spent a few months watching them valiantly avoid sun stoke.

(In reality, exposure is a huge hurtle for baby birds and it’s quite a testament to these and all birds that manage to work around this so they can live near their food source)

After looping to the west of the island and quickly retreating because it smelled like rotten fish guts, we started back. We were leaving Navopatia when we came to shore. I could have stayed; written some Steinbeck sluiced book and found a beautiful Mexican wife who could plump me on hand made tortillas and seviche.

But we had to meet the Mays in Alamos that evening and explore Tropical Deciduous Forest (TDF). Everyone was going to be glad to no longer hear me spout on about “TDF”. It sure was hard living this lavish life of natural history worship

Although I knew I’d be back, it was hard to leave our friends. We’d see all the people from Evergreen back in the Northwest but who knew when I’d see any of the locals again. I made a goal with myself to relearn Spanish and find my way back soon and actually communicate more than monosyllabically. My flailing attempts to do eloquent justice the Thornforest, Navopatia, and the Mangroves won’t suffice. Whoever is out there reading this will have to visit. Really that’s the point of all this laborious self-indulgent verbage – to inspire you to explore and care about our world.

“Probably every subject is interesting if an avenue into it can be found that has humanity and that an ordinary person can follow.” – William Zinsser, Writing to Learn

That about sums it up!

Mexico Part 4 – The Big Labyrinth

Posted in Birding, Birds, Mexico, Natural History, Navopatia Field Station, Plants, Science, Sonora on March 20, 2010 by Brendan McGarry

Exploring mangroves is extremely dependent on the tides.  The water surrounding the island (which is plopped between the Sea of Cortes and Navopatia) is never too deep and you can see sandbars form daily in the channel.  In the less fast moving water, serious stands of mangroves have set up shop.  We’d explored the small labyrinth already, less a paddle through than a pulling and pushing on muddy trunks and stems covered in bird crap.  As our boats staged across the channel, we headed for the Big Labyrinth.

It wasn’t far fetched to imagine becoming  disoriented and experiencing labyrinthine wilderness down some lanes of the mangroves.  But the Big Labyrinth was tame.  Several of us could paddle side by side and a powered fishing boat even came up the channel to set a net.  I wasn’t ever nervous on previous explorations but it didn’t feel as secretive, more like a regular thoroughfare.

My friend Dan Maxwell had arrived the night before, after 32 hours on a bus from Tamaulipas.  He worked on Adam’s Northern Sierras point count crew and had done training with Simone and I in Chester, California.  Incessantly exuberant in a very Californian manner, he couldn’t help expressing his excitement at the Mangrove Warbler, the simplicity of paddling through this habitat.  I was enjoyed having someone to reengage my enthusiasm.

Though I’d only been at Navopatia a few days, I was beginning to slump into a lethargy of familiarity.  Sure there was a lot I’d never seen before but it’s easy to glaze your perception once you’ve come off the high of a new environment.  The energy of childish fascination for nature isn’t hard for me to attain, but it wears me out and I’ll realize I’m not actually observing anymore.  Sometimes I find myself overwhelmed by the questions I have about new places, in which case, for survival’s sake my brain backs me away from the edge of perpetual inquiry.  For better or for worse.

We caught glimpses of what turned out to be a Northern Waterthrush.  All I managed was a dark shape flying across my bow, which landed in the mud bobbing it’s tail before  secreting away into the endless trunks.  Simone and others caught a better glimpse and confirmed.

Attempting to find animals once they’ve  melded into the mangroves was impossible.  I was leading our flotilla when we broke out into a large lagoon.  Startled at seeing a bright monstrous red thing appear inexplicably, every bird within sight fled.  The only Green Heron of the trip skidded into a mangrove, looked back, and silently climbed deeper into the folds.  Seeing this disappearing act reawakened the mystery of these trees.  Anything could be out there.

We all paddled lazily through the shallow lagoon, spreading out and drifting aimlessly.  This was certainly a good life to be have, one to aspire to.  As my boat was turned around in a circle by the flow of water, I counted a Spotted Sandpiper, a Long-billed Curlew, a Marbled Godwit, Willet, Whimbrel, White Ibis, Reddish Egrets, and numerous Yellow-crowned Night Herons.  I didn’t even have to turn my head, I just held my binoculars aloft let the tide pan  for me.

The Night Herons were particularly hysterical.  Apparently the exposed flats were highly covetable.   One bird would look up and see another, distantly going about foraging, and leap into action.  He or she would swoop in to furiously chase the other off, even following them to a new expanse.  In the meantime another bird would have fill the vacant space of the squabbling pair.  The air was filled with the perturbed croaking of herons that appeared to not be doing much in the way of feeding.  Possibly this wasn’t as simple as food and was more lodged in an expanse of territory. However, having watched herons forage in the past,  no one appeared to be despot of a stretch of mud.  Again the tide made sure of that.

Brown Pelicans eyed us as we made our way back.  One pair was particularly calm as Danner floated nearby and I followed.  I suddenly realized that we were at the mercy of this huge bird, not the other way around.  On the slog back to camp, I pondered how much I took being a human for granted.

That night we had some guests arrive that everyone sort of expected.  They’d tried to keep it secret, but Steve Herman and Drew Whellan were personalities too big to try to ferret away.  I had already sleuthed out their arrival but that made me no less excited to have them with us.  Steve had a lot to do with Navopatia, especially seeing that Sallie was his daughter and Adam his son in law.  Dr. Herman also happened to be the Ornithology professor in whose classes we all became friends, joining a colorful and gregarious group of former students dubbed Hermanites.  Normally I don’t buy into idol worship but if I’ve ever met anyone who deserves it, Steve certainly does.   Equally as colorful and enjoyable was Drew, a good friend and fellow Hermanite, was just as stoked to be there as we were.

We finished the night with a rip roarer of a party.  Fire, libation aplenty, and Ranchero music for dancing under the stars.  To say they least, the following day didn’t start early.

Mexico Part 3 – The Ranch

Posted in Birding, Birds, Conservation, Mexico, Natural History, Navopatia Field Station, Sonora with tags , , , , on March 15, 2010 by Brendan McGarry

Danner’s truck skidded through a huge mud puddle and we all held on for dear life.  Speeding through the Pitayal at 7am I couldn’t have felt more contented.  A behemoth above the desert landscape, the fig tree of the ranch loomed ahead.

As AWA began to explore the region in the early days, they found a nearby cattle ranch that was fine with a buncha geeky gringos sneaking around and shouting about “los pajaros.”  With considerable stands of mesquite scrub, a small freshwater creek, a squared man made lake, and the aforementioned fig tree, there were of birds aplenty.  They were chattering away as we made our way towards the lush creek banks sloughing warblers and the fruit heavy fig.

Kiskadees and Gila Woodpeckers were making a ruckus gorging fruit.  Behaving much more respectably and frustratingly cryptic was a species I’d long wanted to see, the Rufous-backed Robin.  For a millisecond birds would pop into view and stuff their faces, before disappearing behind the shroud of leaves.  Someone said something about them “just being robins,” as I sat patiently enduring their infuriating shyness.

Along the lakeshore we found masses of Lark Sparrows.  I’d never seen so many in my life; they were in small flocks of six or eight birds and seemingly everywhere.  Seeing huge amounts of migrant birds was surprisingly one of my favorite things about Mexico, (considering that I enjoy birds largely because of their ecology and not for the baseball aspects of birding, this actually isn’t a surprise at all).  Imagining the odyssey rivaling journeys that these birds endured to arrive at Navopatia, knowing that possibly they’d even be from Washington State boggles the mind (which end of their migration are they actually from anyway?).  Seeing clouds of Orange-crowned Warblers of the same subspecies that breed in the Northwest continued to enliven imaginative drifting on avian life.  It certainly put the rest of us humans in our place.  As if to keep reminding me that we were still in North America and that, yes most of these birds could be seen within 100 miles of where I live, a male Bufflehead screamed down to land.

Neotropic Cormorants bobbed up and disappeared beneath the murky surface of the lake.  At the far end, Least Grebes sat nicely along with Pied-billed Grebes accommodating those who were new to them.  Mexican Mallards floated together like any other mallard pair would, despite their practically imperceptible dimorphism.

Vermilion Flycatchers are so stunning that I think they overwhelm people.  Danner and I followed a male around snapping shots as he patiently went about his day. It was too easy to see these birds everywhere and get dulled to their stunning red and black plumage – but being a pale, color starved Northerner I couldn’t get enough.  People may balk at that statement and suggest some notable birds that display the shade, but no I’m sorry, there’s nothing so brilliantly crimson in Washington.   After probably 80 photos of this little gentleman, I got distracted and went off to find a Harris Hawk that had flown by with nest material clutched in it’s talons.

A couple ranch hands rode by on horses, friendly enough but seeming a bit suspicious of the bunch of us.  I couldn’t blame them.  Despite the natural wealth of the land here, everyone living on this ejido (land made communal by the government) was poor.  Here we were, a bunch of kids running around with binoculars, scopes, cameras, things that would cost many people here more than a years salary.  It reminded me of a time in Ecuador when our group stood watching some gaudy, extraterrestrial bird in awe of the exquisiteness of nature, when a group of cattle ranchers drove their cows past our group.  Wearing torn clothes, their cows visibly infested with bot fly larvae, it was immediately hard to feel happy about this place.  These Mexicans weren’t unhappy and probably weren’t starving but I couldn’t help but feel a wash of guilt about my luck.

It was easy enough to slip back into my astonishment of birds and nature almost as a remedy for such feelings.  A Bell’s Vireo sang in a clump of mesquite and I succumbed to my excitement once again.   But I didn’t want to completely forget about the disparity of the world and the fact that this is not only horrible for people but the environment as well.  I used to think that we couldn’t help the environment without first helping people.  While that is conditionally true the simplicity of that view doesn’t permit a holistic approach.  Considering people and place separate, animals apart from people, won’t solve problems but more likely than not actively promote the downward spiral.  Health of the environment means health of the people.  While I’m not suggesting a Utopian ideal, it’s obvious that when the air is clean and the water clear, people are better off.  What makes me ashamed of my economic status more than anything is knowing that it is built on the backs of people like this and that companies knowingly continue to callously ruin people and place for things like Pop Tarts and TV Dinners.

I continued to think about this as we headed back to Navopatia.  Ahead, six Harris Hawks started from some particularly tall pitaya and my mood lightened a bit.  Life strode on in the face of everything people thrust upon it and ultimately no matter what happens to us, nature will get through the human hiccup.  That doesn’t meant can sit back and watch it all fall down but it’s comfort knowing that people are still part of a system we neither control or completely understand.  My awe of this planet will never cease and neither will my drive to make it a better place for all considered.  Face to face with biodiversity and environmental strife in the pitayal, we slowed to watch an immature Gray Hawk just before returning camp ward.

Mexico Part 2 – Desert Banding

Posted in Bird Banding, Conservation, Field Work, Mexico, Natural History, Navopatia Field Station, Sonora on March 8, 2010 by Brendan McGarry

Once I’ve found a routine for early mornings, I happily adhere to them, especially to see some birds close!  Bird banding dictates early mornings for several reasons.  Birds are more active on cool mornings in hot clines.  Setting up nets at daybreak means birds don’t see nets being set up by loud clumsy apes and can avoid them. Finally banding birds in the heat of the day is dangerous for them because they are put in a stressful situation without food or water.  This final reason is the calculated risk taken to gather important data and responsible banders will cancel readily.

Our first foggy morning the crew was supposed to be out netting birds near the road into Navopatia.  But heavy fog soddens nets, which will soak birds.  Deserts aren’t even vaguely warm before the sun is of sufficient height and this combination can kill.  Nothing makes a bander more upset than losing birds unnecessarily (except maybe cows walking through your expensive mist nets).  Life is always in the balance and I’m not unduly sentimental about natural death.  But being the hand that dealt or even a part of any operation where a mistake happens (this is very rare) is devastating.

Some people might have objections to handling birds, suggesting that it’s an unnecessary stress on birds and that we can learn through passive observation.  While I agree there is still plenty of extrapolation from point counts and area searches to be had, banding provides a massively in-depth look into the life of birds and accurate population samples.  According to USGS and the National Bird Banding Laboratory approximately 1.1 million birds were banded in 2001, with 689,019 being non-game birds.  Of those birds only 8057 were recovered and reported (ie found dead, collected for a museum, etc.).

Now I’m not saying 8,057 dead birds is completely trivial especially when they were all banded but this is only .1% of the total caught.  This also doesn’t mean banding was the  source of mortality.  More birds than that probably die but I’ve never seen any good evidence that responsible operations are a major stress on avian survivorship.  On the contrary the research of the Monitoring Avian Productivity and Survivorship (MAPS) and Monitoreo de Sobrevivencia Invernal (MoSI, the program AWA bands for) lead to significant knowledge on population health.

Although I wanted to see some good banding action, vacation was still on the forefront of my mind.  Rising at a late 7:30AM and strolling to the banding site was just fine for me.  Because the capture rates were typically low, I wasn’t going to band anything myself anyway.  The experience of handling birds is magical and since it was at a premium, I knew the students/field workers were eager for as much as possible.  I decided I’d just join the bird paparazzi, photographing birds in the hand is tons of fun.

Simone and Oliver had gotten in late the night before, having traveled down with Oliver’s parents separately.  We weaved down the road, distracted by every little thing along the way.  It was already starting to heat up.

When we got to the banding tent, Mandy, one of the interns, already had a Streak-backed Oriole.  This was a bird I’d actually never seen before and although it was beautiful, it made me anxious to try to find one out of the hand (I’d eventually see a pair of them auspiciously close while sitting on the open air toilet in camp!).  Like many birds, you get a real grasp of actual size when their necks are clasped between your middle and pointer fingers.  Such colorful animals appear literally larger than life when they are drinking nectar from a Pitaya bloom.

A female Northern Cardinal came in shortly after, along with its cousin a female Pyrrhuloxia.  For congeners, their resemblance close up isn’t cut and dry.  A Pyrrhuloxia has its parrot-like orangish bill, giving them a subdued expression.  Cardinals (forgetting the obvious difference that males are painfully crimson in comparison to the only red highlighted male Pyrrholoxia) have a broader and longer pointed red bill.  The difference in bill size and shape eludes me because I know both are well adapted to crushing seeds and both have similar feeding habits.  A guess might be that the Pyrrhuloxia due to arid obligation uses the likely more fierce leverage of a parrot-like bill on thicker husked desert seeds and more heavily armored desert insects (making an assumption that desert seeds and insects layer against desiccation).  And maybe I am just exaggerating the differences of their bills.  I admit that in silhouette, these birds are almost inseparable.

More birds continued to come in.  It looked like this wasn’t a slow morning.  Another potential lifer, a Black-capped Gnatcatcher was quickly processed.  A bird that couldn’t be banded with AWA’s federal bands (because each state separately administers their populations), a female Gambel’s Quail got caught in the net.  Offering a unique looks at it’s captivating blood-red eye and extensive patterning a Cactus Wren was brought in.

The final bird before I decided to head back for breakfast (I’d already been feasting on leftover tamales from the night before) was a male Gila Woodpecker.  You could hear this bird from moment it came into earshot and the screaming didn’t cease till we released it.  Most people thought Adam was joking when he said he hated them but having banded plenty of talkative woodpeckers, I could relate.  Still I couldn’t help but admire the smooth cream-colored head and underside in comparison to a heavily pied topside.  A tarantula-hawk that had been following me around unnervingly had thankfully switched interest to this hysterical bird as it buzzed close.

In retrospect I am kicking myself for not joining the banding operations everyday during the trip. The MoSI program isn’t run like MAPS, whose banding stations I have worked in since high school.  They run pulses of 2-3 days in a row, with 16 nets set.  MAPS will typically make regular single day samples of various regional sites or a continuous period of banding in one location.  MoSI is essential because it connects data from breeding grounds in the US and Canada with wintering sites in the Neotropics.  Not understanding winter grounds would be very short-sighted considering that half of the bird the bread in temperate North America winter in Mexico and beyond.  This was a great opportunity to see birds I’d never handled before or even seen in the hand.  As soon as I left they caught a male Varied Bunting a bird exhibiting a glory of both structural and pigmented coloration.  The next day they had a Greater Roadrunner and Black and White Warblers!

Mexico Part 1 – Into the Magrove Labyrinth

Drops of water kept falling on my face.  I tried to roll over and cover up with my sleeping bag but instead nuzzled a pool collected at a low spot on the floor of my tent.  Cactus Wrens churred away and Curve-billed Thrashers whistled their double note call mere paces away and Whimbrels screamed incessantly only a bit further off.  Here I was rolling around in a soppy tent.  The sun was up, time to rise.

After driving nearly 700 miles – from Madera Canyon in Southern Arizona to within a short hike of the coastal Sonoran-Sinaloan border, I wasn’t quite expecting this.  Sore from the slog south, squeezed into various seats with my friends Alison, Jeff, and Jenny in my friend Danner’s truck, I was ready for some sunshine and lots of birds.  Somehow there was enough fog that I couldn’t see past the two tall cacti next to my tent.

We’d gotten to Navopatia late the night before after braving some seriously boggy roads.  Apparently our friends at the field station had endured epic rainfalls unusual in duration and frequency.  The field station was far from running water and a truck delivered non-potable uses.  Trucks hadn’t been able to get in and they’d not been able to leave to get drinking water either.  Things were actually looking a bit serious.

Fog and a weeklong bout of torrential rain in the Sonoran Desert?  This wasn’t the winter Mexico I’d expected.  I needn’t have worried; we weren’t in for anything but spectacularly pleasant sunshine.

Almost everyone else was up wandering about.  The other vehicle in our convoy included my friends Sarah and Alex, the latter of whom was still sleeping off a jetlag from a flight back from New Zealand.  Those of us who’d never visited before stumbled about wide-eyed.  Several mystical looking White Ibis flew by, pink faces glowing in the ethereal light.

Everyone was dumbstruck by the fog, truthfully quite beautiful, creating dew on all the vegetation and casting a wonderful glow about everything.  I noticed lichen growing on all the tall plants nearby apparently thriving off coastal moisture, a floral arrangement quite unexpected.  The horizon was like nothing I’d ever seen, cactus crowns towering above all else.  A jumble of skyward spires lined my scope in all directions except over the water to the west.

I had already seen two new birds – Mangrove Swallow and Yellow-footed Gull.  The bird life just at the beach of the field station was astounding.  Several species of Terns, large numbers wading birds from over wintering shorebirds to resident herons and egrets, and oh the songbirds.  Pyrroloxia, Orioles, Gnatcatchers, Towhees – a surprising number of songbirds wintering from the north.

Our friends Adam and Sallie soon found their way down from camp to greet us.  They have been doing research here at the Navopatia Field Station through their non-profit, which they founded with several others, the Alamos Wildlands Alliance (AWA).  Along with Heather (and others I will get to), my friend Oliver’s elder sister, they are currently running the field station and working toward the goal of preserving this fascinating and important landscape.

Adam’s master’s thesis is on the importance of Costal Thornscrub (the gringo name for the habitat) for over wintering migrants.  The local name is the Pitayal, from the physically dominant, organ pipe cactus or Pitaya (Stenocereus thurberi).  With several other species of cacti and multiple decidedly thorny shrubs all typically never growing higher than 20 feet, Thornscrub is appropriately descriptive.  I still think “scrub” is a drab descriptor for a landscape so immediately alien and exciting.

As the fog lifted a bit, I couldn’t help but break into a shit-eating grin at the glory of it all.

We weren’t going to waste any time sitting around just yet either.  There were the mangroves and here were some kayaks.  Time to explore.  We paddled across the water to the bank of the saline forest surrounding the main island in the Agiabampo Estuary.  Reflecting that this was a habitat I’d seen so often in my travels but I knew so little about except some cursory facts, I reminded myself to steady my excited pulse and to try to observe more effectively.  Into the labyrinth our throng of boats went.

Clams clapped closed and we paddled through the narrow waterway.  Crabs painted stunning blue and red clung to the mangrove roots and scuttled to the opposite side and out of sight as we passed.  Tidal fluctuations obviously dictate the ecosystem and there was a different feeling of fluidity about everything, nothing like landlocked habitats.  Filtered sunlight crept through the low canopy of yellow-green leaves, giving one the impression that many secrets were held deep in the trees.

I could hear Mangrove Warblers; a decidedly recognizable subspecies of Yellow Warbler that is so different with its reddish head, distinct song, and specialized habitat that I swear it deserves splitting.  And I’m not saying this just because I want another bird to have on my life list.  Sure they’d breed with other Yellow Warblers (females are largely the same) but can you really deny the separation their obligation creates?  I suppose now I need to look at the research!

Another lifer I never did see was a Mangrove Vireo, though I heard them a couple times as we pushed and pulled through the aptly named little labyrinth.  It eventually opened up and I had spectacular views of male Mangrove Warblers singing from the highest points they could find.  It didn’t matter that I’d forgotten sunscreen (winter in the Pacific Northwest leaves me cadaver pale) and that my butt was sloshing about in the brackish bottom of my self-bailing boat.  Day one certainly wasn’t a bust.
