This was the inaugural tour of this route! As can be expected, we had a few hiccups, but it was a success overall. The purpose of the tour was to visit the parts of the state of Oaxaca that we had been ignoring on our long-running tour of the central valley around Oaxaca city. The valley area provides some great birding, of course, not to mention cultural highlights. But the state of Oaxaca is one of the most biologically diverse of any political unit in North America! The state, for us US-centric folks, is only a bit larger than Indiana, yet has the number of bird species regularly encountered in the lower 48 US states: around 750! Why is this? Well, location, habitat diversity, and complex geologic relief all play roles, as does the strategic placement of Oaxaca: just near one of the most important constrictions of the North American continent: the Isthmus of Tehuantepec. Because of the narrow nature of the isthmus, this state has both Pacific and Atlantic (in this case, Gulf of Mexico) slopes! The only other Mexican state to have both (and a coastline) is Chiapas. Thanks to the various mountain ranges, valleys, the prevailing trade winds (which blow from the east at this latitude), and the Pacific coastline, this results in a mosaic of humid and dry conditions, rainshadow valleys, deserts at higher and low elevations, and great circumstances for local endemism in birds (as well as other, more sedentary organisms!). One top of all the diversity among resident birds, there is an additional and important component: boreal migrants! We enjoyed seeing a lot of “our” birds on their wintering grounds here. It really helps us comprehend the life histories of these migratory species to see them where they spend their “winter” months, as well as in the act of migration. Our checklist is a testament to this diversity, as it sported nearly 550 potential bird species and we encountered about 380 in the space of about 10 days! Not bad at all!
Our route played a role in this impressive tally. We started and ended in Oaxaca city, of course, which also gave us a few species we didn’t encounter anywhere else on the route—House Finch, Curve-billed Thrasher, Vermilion Flycatcher—to name a few. Our itinerary first took us south into the Sierra Madre del Sur, where we spent an overnight in the high pine-oak forests around the town of San Jose del Pacifico. It was here that we enjoyed some of the higher elevation montane species of these drier forests. Familiar species such as American Robin, Spotted Towhee, and Audubon’s Yellow-rumped Warbler were side-by-side with Gray Silky-Flycatcher, Bumblebee Hummingbird, and Chestnut-sided Shrike-Vireo. The jangling crescendos of Brown-backed Solitaire were a regular sound. As we crossed onto the Pacific slope and headed lower, we entered a narrow band of humid evergreen forest, a form of cloudforest thanks to the east-west orientation of the range here that catches humidity from the Trade Winds off the Gulf of Mexico, and here we had some truly tropical birds such as the Wagler’s Emerald Toucanet, Eye-ringed Flatbill, and Ruddy Foliage-Gleaner, among others. Lower still, the forest became dry and deciduous, still mostly leafless in March, but nevertheless chock full of interesting birds! Orange-breasted Bunting, Colima Pygmy-Owl, and Spot-breasted Orioles were among the local specialties we enjoyed here. A morning out on the Pacific Ocean itself netted us a whole new assortment of birds—shearwaters, boobies, frigatebirds, for example—which provided an undeniable contrast to the forest birding in the pines only a couple days before! From Huatulco on the coast, we then headed east to the Isthmus of Tehuantepec itself, visiting a lagoon near the coast one evening, and then a patch of deciduous scrub the next morning. The former allowed us to see migrant shorebirds and some coastal terns and gulls. The latter was home to a few of the stars of the tour: Rose-bellied Bunting, Cinnamon-tailed Sparrow, and Lesser Ground-Cuckoo! From these hot lowlands, we worked our way northwest onto the Gulf slope. Here, on the windward side of the Sierra Madre Oriental, we were finally on a truly humid slope, with scraps of lowland rainforest which turned into true cloudforest as we ascended upward in elevation. The diversity here is perhaps the greatest of the tour, and whereas we encountered fewer local endemics (most species are shared with several countries east and south of Mexico), the sheer numbers of species and the presence of truly tropical families such as jacamars, antbirds, and many more members of the furnariids, tyrant flycatchers, and hummingbirds, make it clear that more rainfall really does equal more species! The number of days we spent hardly did justice to the list of species we encountered, but we did enjoy views of some memorable birds just the same! Finally, we headed back to Oaxaca city via the higher pine-oak forest, although our only taste of this habitat was at our final lunch stop at Restaurante Colibri before returning to the city. It was a large loop, and it took us through such contrasts!
Highlights from the tour were many and varied. Some were avian, some were not! Folks mentioned things such as the sheer diversity of habitats, or that fruiting tree at Bethania that seemed to be bringing in nearly all the local birds as we enjoyed a picnic breakfast underneath it, or the acrobatics of the Spinner Dolphins ahead of our boat on the ocean. But the birds overwhelmed us in their color and variety. Highest on the list were local specialties such as the peculiar and highly range-restricted Sumichrast’s Wren, Rose-bellied (or Rosita’s) and Orange-breasted bunting, and the skulky Lesser Ground-Cuckoo that we got in our scopes. Lower down on the list were such experiences as the huge shearwater scrum that we came upon in the boat, with thousands of birds sitting around us on the water, or the comical Brown Booby perched on the back of a sea turtle (which may have been oblivious?), the surprise Nazca Booby that flew past us showing off that saffron yellow bill, or the molting jaegers as they wove through the shearwaters searching for one to harass. In the pine forests of the San Jose del Pacifico area, we were treated to a comparison of the look-alike Chestnut-capped Brush-Finch and Collared Towhee, and to the eye-searing scarlet of the lovely Red Warbler, and got to hear the rollicking songs of Long-tailed Wood-Partridges which failed to come into view, sadly. In the lowland Pacific slope and Isthmian woodlands, a few choice sightings included the elegant White-throated Magpie-Jays, and the pairing of the Sumichrast’s Sparrow and Rosita’s Bunting, which told a love story between Sumichrast, the bird collector from the 1800s, and his wife Rosita, who influenced him to settle in Oaxaca and live out his days. In the Gulf lowlands, a few highlights included the strutting Mayan Antthrush at Bethania, Karen spotting that Tody Motmot in the dark interior of vegetation in that gully, the incredible music of the Slate-colored Solitaires in the cloudforest, and that amazing view of Pheasant Cuckoo over us, not to mention a female Golden-cheeked Warbler that Jorge got us on that last morning! There were so many other great experiences, it is hard to sum them all up in a paragraph, but these memories we will carry with us…
So Micah, Jorge, and I thank you for joining us on this tour. We hope you enjoyed this cross section of one of Mexico’s most amazing states, and will consider joining us again in the future on another great birding adventure! Saludos y buen pajareando (farewell and good birding)!

GOLDEN-CHEEKED WOODPECKER (Melanerpes chrysogenys) [E]
A fairly common woodpecker of the deciduous forests of the Pacific slope.
GOLDEN-FRONTED WOODPECKER (Melanerpes aurifrons)
We had two forms, one that looks quite like the one we know from Texas (but perhaps with more densely-barred back), and one that looks more like a Red-bellied Woodpecker. These intergrade right around where we were in the Isthmus area, and one could see birds of either form (or intermediates) at several sites. Some authorities split these populations from the more northerly ones and call them "Velasquez's Woodpecker".
HAIRY WOODPECKER (Dryobates villosus)
In the pine forests of San Jose del Pacifico, where the local form is smokier below than those we may know in the US or Canada.
PALE-BILLED WOODPECKER (Campephilus guatemalensis)

The Gulf lowlands member of the more lightly-built genus Lepidocolaptes.
SPOT-CROWNED WOODCREEPER (NORTHERN) (Lepidocolaptes affinis affinis)

WHITE-LORED GNATCATCHER (Polioptila albiloris)
The common gnatcatcher, especially around the Isthmus area.
SUMICHRAST'S WREN (Hylorchilus sumichrasti) [E]
Wow, what a cool wren! It looks more like a kiwi, and sneaks around on the limestone walls like a rodent. We enjoyed hearing their loud songs and then playing hide-and-seek with one that may have had a hidden nest nearby in the limestone.
HOUSE WREN (Troglodytes aedon)
A bird at Valle Nacional may have been a northern migrant or a local resident. If the latter, that population is part of a group of subspecies that are called "Tropical House Wren" and are split off from North American migratory forms by some authors.

This was the blackish-crowned form we saw in the Gulf slope cloudforest.
COMMON CHLOROSPINGUS (SOUTHWEST MEXICO) (Chlorospingus flavopectus albifrons)
And this was the grayer-crowned form we saw on the Pacific slope. This species is a very widespread montane bird (formerly called "bush-tanager" but now known to be an American sparrow!) found from Mexico to Argentina. No doubt, the complex will be split into many species, so it's worth keeping track of which ones you see for when that moment comes.
CINNAMON-TAILED SPARROW (Peucaea sumichrasti) [E]
Also called "Sumichrast's Sparrow" and endemic to a small area on the Pacific side of the Isthmus. We had great views of the bird at Ojo de Agua.

A peculiar canopy grosbeak of Gulf slope lowland forests, we had this well at the Bethania site.
NORTHERN CARDINAL (Cardinalis cardinalis)
What a looker here! These are the "Long-crested Cardinal" form of the Pacific coast that are super-red on the males and cinnamon without much red (except the bill) on the females. The latter also sport an obvious black mask, unlike the forms we know in the US. They are a feature of the deciduous forests around Huatulco.
ROSE-BREASTED GROSBEAK (Pheucticus ludovicianus) [b]
Mostly on the Gulf slope.
BLACK-HEADED GROSBEAK (Pheucticus melanocephalus) [b]

RED-BREASTED CHAT (Granatellus venustus) [E]
Long considered a wood warbler, this genus (with three species, including one on the Yucatan and another in South America) is now known to be a member of the bunting and cardinal family! Its voice is a dead giveaway.
BLUE BUNTING (Cyanocompsa parellina)
We had fleeting glimpses on the Pacific slope in the deciduous woodlands there... and after relistening to my recordings from Bethania, I realized I had been calling it "Blue-black Grosbeak!" So if you heard that there, it was in fact Blue Bunting!
BLUE GROSBEAK (Passerina caerulea) [b]
INDIGO BUNTING (Passerina cyanea) [b]
A fairly common migrant we saw on the Gulf slope especially.
ROSE-BELLIED BUNTING (Passerina rositae) [E]
This, the Rosita's Bunting, is one of the highlights of the tour, and we certainly had great views of this electric blue and pink beauty (and the more modestly-plumaged females, which are lovely in their own right!) at Ojo de Agua.
ORANGE-BREASTED BUNTING (Passerina leclancherii) [E]
More widespread along the Pacific slope, we nevertheless saw it best at Ojo de Agua alongside the last. Hard to decide which species is more impressive! So, let's not rank them, and simply enjoy them.
PAINTED BUNTING (Passerina ciris) [b]
Seen on both slopes, but particularly on the Gulf slope, including a few colorful males.
CRIMSON-COLLARED TANAGER (Ramphocelus sanguinolentus)

This and the next species were around Valle Nacional.
YELLOW-WINGED TANAGER (Thraupis abbas)
GOLDEN-HOODED TANAGER (Stilpnia larvata)
Our only "Tangara" tanager, although that genus has recently been reorganized and this one is no longer within it... but so what, I'm still calling it a "Tangara"!
RED-LEGGED HONEYCREEPER (Cyanerpes cyaneus)
A really fetching species we encountered on both slopes in evergreen forest. Those flashing yellow underwings of the males are surprising!
CINNAMON-BELLIED FLOWERPIERCER (Diglossa baritula baritula)
A tanager that steals nectar from hummingbird flowers with the help of its bill. We had this one at San Jose del Pacifico.
BLUE-BLACK GRASSQUIT (Volatinia jacarina splendens)

Also at the same spot as the last two. Must have been a very seedy place!
BANANAQUIT (Coereba flaveola)
Not uncommon on the Gulf slope.
YELLOW-FACED GRASSQUIT (Tiaris olivaceus)
Also at the same spot as the various seedeaters above.

TAYRA (Eira barbara)
A couple of folks caught a glimpse of this large weasel relative our last morning as we birded the last spot in the cloudforest before heading on to lunch. Too bad it didn't come back in to squeaking.
Totals for the tour: 379 bird taxa and 8 mammal taxa
