A great way to spend the Christmas holiday is in a place with friendly people, breathtaking landscapes, mouthwatering food (and drink!), and, of course, amazing birds?! There are few places easier to achieve this than Oaxaca, Mexico, and this year’s Christmas tour experience bore that out.
Based out of our comfortable bird-and-butterfly-filled hotel grounds in the city of Oaxaca for the entire week, we were able to explore the Oaxaca valley from the low dry cactus desert all the way up to the pine and humid evergreen forests of the high (>10,000 foot) mountains. By covering such a broad elevational range, we found a diverse selection of birds, from dry-country specialists like the brilliant Orange-breasted Bunting and shy Russet-crowned Motmot, to montane birds such as the iconic Red Warbler (which was voted the top bird of the trip at the end of the tour). We also sampled many of the culinary pleasures of Oaxaca. Chapulines (cooked grasshoppers) were not most people’s cup of tea, so instead we sampled the dizzying array of delicious mole (pronounced Mō-lay) available in Oaxaca (known as the land of the seven moles), as well as scrumptious Quesillo (Oaxaca Cheese), the world-famous regional hot chocolate, and lots of other tasty delights.
This region is the cradle of one of the America's more impressive civilizations, the Zapotecs, and also was peripheral to the later Mixtec and Aztec civilizations. Importantly, it is believed to be where one of the most important events in American (and thus World) human history: the invention of maize or corn! We were able to visit a few of the Zapotec ruins around the valley, see how Mescal is produced from plant to bottle, learn about seven types of mole sauces, and how natural dyes were made for wool weaving. Even a stop to see the world's largest Montezuma Bald-cypress, the great Tule tree, was on the itinerary!
The isolated nature of the dry Oaxacan valleys in between several mountain ranges means that there are several region-specific endemics. Some of these are easier than others, and we found the more common and conspicuous ones right off the bat: White-throated Towhee, Dusky Hummingbird, Boucard’s Wren, and Gray-breasted Woodpecker. Their supporting cast was plenty diverting too, with plenty of vibrantly colored Vermilion Flycatchers, perching conspicuously on fences, wires, posts, and even buildings, and lots of neotropical migrant warblers spending their winter in the dry scrub punctuated by cacti.
The mountains surrounding the Oaxaca Valley provide much of the avian diversion on this tour, and we visited two sections of mountainous terrain: Cerro San Felipe, and the road between Teotitlan and Benito Juarez. Both areas hosted large concentrations of wintering migrants, with very high numbers of Townsend’s and Hermit Warblers in the pines, Nashville and Wilson’s Warblers lower, Hammond’s Flycatchers, Greater Pewee, and even Louisiana Waterthrush. Resident species which we ran into repeatedly included Slate-throated Redstart, Rufous-capped Warbler, Crescent-chested Warbler, Tufted Flycatcher, Greenish Elaenia, and Chestnut-sided Shrike-Vireo. Cinnamon-bellied Flowerpiercer, and Amethyst-throated Mountain-Gem were a couple of the scarcities we ran across up here, and we also finally got some good looks at the shy and retiring Rufous-capped Brushfinch here as well.
Our two visits to Cerro San Felipe, the mountain on the northern doorstep of Oaxaca City, provided a bevy of high elevation denizens, including the range-restricted endemic Dwarf Jay. We also sorted through the constant sounds of White-eared Hummingbirds and Mexican Violetear to find Strong-billed Woodcreeper, Gray-barred Wren, Chestnut-capped Brushfinch, Black-headed Siskin, and Collared Towhee. Olive-sided Flycatcher was a surprising find at the end of our time on the Yuvila road, and our nocturnal excursion led to phenomenal views of Mexican Whip-poor-will and Flammulated Owl (as well as an interesting view of a night-roosting Band-tailed Pigeon). The mountains also furnished us with repeated views of Red Warbler, which won the voting for favorite bird of the trip, and with good reason. It is astonishing to see this little bright red gem flitting around amidst the innumerable muted green tones of the montane forests.
Our morning trip to a dry canyon towards the Pacific coast provided us with several dry desert specialists, including White-lored Gnatcatcher, Green-fronted Hummingbird, Orange-breasted Bunting, and the fan favorite Russet-crowned Motmot, all in the shadow of some impressive columnar cacti.
The dryer, lower slopes surrounding the valley furnished us with the endemic Oaxaca Sparrow, and its good-looking cousin Bridled Sparrow, as well as the Oaxaca special vireo trifecta: we saw Golden Vireo several times, but it took some work to finally get good close views of Slaty Vireo and an exceptional experience with Dwarf Vireo. We encountered these latter two difficult-to-see species on the slopes below the fascinating Zapotec ruins of Monte Alban, showing just how much breadth of interest can be accommodated in this wonderful region.
The variety of habitats we visited in the relatively small area of the Oaxaca valley and its surroundings are the reason for the diversity of birds and other wildlife. The strong humidity gradient, from the desert valley floor and Pacific slope habitat of KM 77 to the deciduous scrub and oak woodland of the mid slopes of the valley, then the drier pine-oak forest of the slopes near Teotitlan, and finally those impressive forests of pine-oak and Douglas Fir on the ridges of Cerro San Felipe. Standing in the shade of those amazing forests, it can be hard to conceptualize that only a few tens of kilometers away is columnar cactus-dominated desert! But such is Mexico, a country blessed with much diversity, culture, and beauty. We hope you all enjoyed our visit as much as we did, and that we see you again soon with binoculars in hand and adventure in your eyes!

Many at Presa Piedra Azul.
ROCK PIGEON (Columba livia) [I]
BAND-TAILED PIGEON (Patagioenas fasciata)
This high elevation pigeon can be tricky to track down, especially in winter, but Brian spotted a bird roosting in the pines on Cerro San Felipe at night while we were owling. There was also a briefly seen flyby while we were driving up the Teotitlan mountain road during our second visit there, though it didn't stick around.
INCA DOVE (Columbina inca)
In towns. Named incorrectly (it was meant to be "Aztec Dove" but someone forgot which civilization was in Mexico...
COMMON GROUND DOVE (Columbina passerina)
A couple of these dry country doves with the helicopter wingbeats at KM 77.
WHITE-WINGED DOVE (Zenaida asiatica)
MOURNING DOVE (Zenaida macroura)
A few at our first few stops below Teotitlan put this bird on our checklist.
GROOVE-BILLED ANI (Crotophaga sulcirostris)
A cluster on the side of the highway on our first birding day was a serendipitous encounter, since we don't spend much time birding in the disturbed habitats that they call home here.
MEXICAN WHIP-POOR-WILL (Antrostomus arizonae)
Great views of two birds on Cerro San Felipe.
WHITE-COLLARED SWIFT (Streptoprocne zonaris)
A cluster of large swifts zipped over us at El Colibri restaurant and they predominantly, or all, were this species.
MEXICAN VIOLETEAR (Colibri thalassinus)
Formerly called Green Violetear, until South American populations were split off (those renamed "Lesser Violetear"). These sing incessantly around blooming Salvia patches.
RIVOLI'S HUMMINGBIRD (Eugenes fulgens)

Seen on most days, these birds appeared mostly to be the local subspecies hadropus with their rufous-washed vents.
FLAMMULATED OWL (Psiloscops flammeolus) [b]
All right! This small migratory owl can be a real bear to see... but we managed to lock our eyes on one of two we heard and enjoy it through the scope until finally walking away from it!
NORTHERN PYGMY-OWL (MOUNTAIN) (Glaucidium gnoma gnoma)
Often diurnal, and that's how we saw it.
NORTHERN SAW-WHET OWL (Aegolius acadicus) [*]
One squealed in response to playback, but never showed, unfortunately.
MOUNTAIN TROGON (Trogon mexicanus)

LADDER-BACKED WOODPECKER (Dryobates scalaris)
HAIRY WOODPECKER (SOUTH MEXICAN) (Dryobates villosus jardinii)
A few views of this one in the pines on Cerro San Felipe and above Teotitlan. Smokier-looking than most populations to the north.
NORTHERN FLICKER (RED-SHAFTED) (Colaptes auratus mexicanus)
Wow, after commenting that we "never see flickers"... one perched out on a limb allowing scope views!
CRESTED CARACARA (Caracara cheriway)
The "Mexican Eagle" is a common sight as we drive the roads along the floor of the valley.
AMERICAN KESTREL (Falco sparverius) [b]
MERLIN (Falco columbarius) [b]
Harassing shorebirds at Piedra Azul.
PEREGRINE FALCON (Falco peregrinus) [b]

NORTHERN BEARDLESS-TYRANNULET (Camptostoma imberbe)
One on the hotel grounds, another at the pond above Teotitlan, and another pair at KM 77... that's more tyrannulets than I think we've every clocked on one tour!
GREENISH ELAENIA (WEST MEXICO) (Myiopagis viridicata jaliscensis)
One showed very well near the pond at Teotitlan, but a surprise was a bird up in the pine-oak forest of Cerro San Felipe.
TUFTED FLYCATCHER (MEXICAN) (Mitrephanes phaeocercus phaeocercus)
This cute cinnamon pewee was present at several sites.
OLIVE-SIDED FLYCATCHER (Contopus cooperi) [b]
Wow, nice find! This Boreal pewee was at the field on the Yuvila Rd. Not a regular species at this time of year, but they do occasionally winter into central Mexico.
GREATER PEWEE (Contopus pertinax)
Seen at several points in the mountains. Unusual was one on the ground at Pollo Nino.
HAMMOND'S FLYCATCHER (Empidonax hammondii) [b]
The common Empid in the montane pine-oak forests.

GREAT KISKADEE (Pitangus sulphuratus)
This large and boldly marked species has increased in the valley since I first started coming to Oaxaca in 2000.
SOCIAL FLYCATCHER (VERMILION-CROWNED) (Myiozetetes similis texensis)
Like the last species, which it looks like, coincidentally, this too has increased very much in presence in the valley.
TROPICAL KINGBIRD (Tyrannus melancholicus)
Mostly around town, but one that flew over the lower switchbacks at Teotitlan was a surprise.
CASSIN'S KINGBIRD (Tyrannus vociferans) [b]
A common wintering species in the valley.
THICK-BILLED KINGBIRD (Tyrannus crassirostris)
Sometimes hard to encounter, we did so most days of the tour.
WESTERN KINGBIRD (Tyrannus verticalis) [b]
One seen well at Monte Alban.

The easiest of the three endemic vireos; we had this our last three days, including on the hotel grounds.
SLATY VIREO (Vireo brevipennis) [E]
A lucky find our last day below Monte Alban, this looker really gave us a nice view!
DWARF VIREO (Vireo nelsoni) [E]
At the same place as the last, we had this Ruby-crowned Kinglet look-alike in the scrub below Monte Alban.

Another Ruby-crowned Kinglet look-alike, but found in the pine-oak forests of the mountains.
CASSIN'S VIREO (Vireo cassinii) [b]
BLUE-HEADED VIREO (Vireo solitarius) [b]
Interestingly, I think this former "Solitary Vireo" outnumbered the other two species on this tour... usually, it is the rarest.
PLUMBEOUS VIREO (Vireo plumbeus)
WARBLING VIREO (Vireo gilvus) [b]
A common wintering migrant in most habitats.
LOGGERHEAD SHRIKE (Lanius ludovicianus)
Getting to the southernmost point of shrike range in the Americas.
DWARF JAY (Cyanolyca nanus) [E]
We had fleeting views on our first visit to Cerro San Felipe, but our second visit netted us far more satisfying views of this Cardinal-sized jay.
STELLER'S JAY (CENTRAL AMERICAN) (Cyanocitta stelleri coronata)
This blue-headed form is quite easy on the eyes.
WOODHOUSE'S SCRUB-JAY (SUMICHRAST'S) (Aphelocoma woodhouseii sumichrasti)
COMMON RAVEN (Corvus corax)
A couple birds flew over the pond above Teotitlan.
MEXICAN CHICKADEE (Poecile sclateri)
The only chickadee in most of Mexico.
BRIDLED TITMOUSE (Baeolophus wollweberi)
For some strange reason, this species is soooo much harder to see here than in Arizona! I have no idea why.

VIOLET-GREEN SWALLOW (Tachycineta thalassina) [b]
RUBY-CROWNED KINGLET (Regulus calendula) [b]
Found in mixed flocks in the mountains.
BROWN CREEPER (ALBESCENS/ALTICOLA) (Certhia americana alticola)
The local form here is resident. Studies are starting to show that Brown Creeper might be best considered several species, so bank this one for later should there be a split!
BLUE-GRAY GNATCATCHER (Polioptila caerulea) [b]
Most of the birds here were probably migrants from eastern USA and Canada, but there is a local breeding form too.
WHITE-LORED GNATCATCHER (Polioptila albiloris)
Found only at KM 77 on this tour, but it is plenty common there!
ROCK WREN (Salpinctes obsoletus)
Several around the ruins at Monte Alban.
HOUSE WREN (BROWN-THROATED) (Troglodytes aedon brunneicollis)

RUSSET NIGHTINGALE-THRUSH (Catharus occidentalis) [E]
We were lucky to see this thrush at Rio Verde our first day... they were very hard on Cerro San Felipe.
HERMIT THRUSH (Catharus guttatus) [b]
At Cerro San Felipe.
CLAY-COLORED THRUSH (Turdus grayi) [I]
This and Rufous-backed are thought to be introduced into the Oaxaca valley from opposite coasts of Mexico, with Clay-colored from the Gulf Coast.
AMERICAN ROBIN (MIGRATORIUS GROUP) (Turdus migratorius phillipsi)
With almost no fruit in the mountains, we encountered this species at the surprisingly low Monte Alban!
RUFOUS-BACKED ROBIN (Turdus rufopalliatus) [I]
Apparently introduced to the valley, but from the Pacific Coast.
GRAY SILKY-FLYCATCHER (Ptiliogonys cinereus)
A handsome and garrulous species we enjoyed seeing at several spots.

Now in its own family, this is not a rare species in the pine-oak forests.
HOUSE SPARROW (Passer domesticus) [I]
AMERICAN PIPIT (Anthus rubescens) [*]
ELEGANT EUPHONIA (Euphonia elegantissima)
Euphonias and Chlorophonias have been placed in the finch family with goldfinches and siskins. More recently, this species and other blue-naped euphonias have been reclassified as Chlorophonias!
HOUSE FINCH (COMMON) (Haemorhous mexicanus roseipectus)
The House Finches in Oaxaca are this subspecies, and have highly contrasting red and gray-brown plumage, which can catch the unaware off guard.
RED CROSSBILL (Loxia curvirostra stricklandi)

Good views at our spot on the road to La Cumbre.
SPOTTED TOWHEE (MACULATUS GROUP) (Pipilo maculatus oaxacae)
A local breeding population.
COLLARED TOWHEE (Pipilo ocai) [E]
This species looks rather like the Chestnut-capped Brushfinch, but its behavior makes it hard to confuse with it!

YELLOW-RUMPED WARBLER (AUDUBON'S) (Setophaga coronata auduboni) [b]
Far more common than the last, including on the hotel grounds.
BLACK-THROATED GRAY WARBLER (Setophaga nigrescens) [b]

CINNAMON-BELLIED FLOWERPIERCER (Diglossa baritula baritula)
Wow! We had at least two adult males at some of the larger Salvia banks near Benito Juarez! That is not an easy plumage to see (heck, the species itself is easy to miss)!
MEXICAN GRAY SQUIRREL (Sciurus aureogaster)
Our only mammal of the tour, and primarily on the hotel grounds.
Blackbelly Racerunner (Aspidoscelis deppii): the striped lizard we saw at KM 77.

BUTTERFLY LIST (compiled by Ahmet Baytas)
Taxonomy and nomenclature follow BUTTERFLIES OF MEXICO AND CENTRAL AMERICA by Jeff Glassberg.
Papilio garamas. Magnificent Swallowtail. A few individuals were always on hotel grounds; also one in downtown Oaxaca.
Battus polydamas. Polydamas Swallowtail. One individual on two separate days on hotel grounds.
Papilio sp. Giant/Thoas type swallowtail flying over trees on hotel grounds.
PIERIDAE- WHITES AND YELLOWS
Catasticta flisa. Narrow-banded Dartwhite. 2 at Benito Juarez. The population here has a small forewing white cell spot (normally not on this species) on the uppersides. I call this C. flisa, but the Butterflies of America has it as a new species described in 1984, C. oaxaca, Oaxacan Dartwhite.
Catasticta nimbice. Mexican Dartwhite. Most dartwhites we saw at Benito Juarez and elsewhere was this one (has a large cell spot on the forewing above and a broad median white band).
Leptophobia aripa. Common Greeneyed-White. This is the white at higher elevations; fairly common at Benito Juarez.
Appias drusilla. Florida White. One at Benito Juarez.
Ascia monuste. Great Southern White. Small numbers at lower elevations where it generally is the default white. Some females on hotel grounds seemed to be looking for hostplants.
Hesperocharis sp. Tilewhite sp. There are 2 high altitude species that belong to this genus of whites that are quite large. We saw several individuals flying around, but none stopped, hence no positive ID.
Nathalis iole. Dainty Sulphur. Small numbers at hotel grounds, Benito Juarez, KM 77 and Monte Alban.
Colias cesonia. Southern Dogface. Several at Benito Juarez.
Phoebis sennae. Cloudless Sulphur. One or two on most days at lower altitudes—always flying fast.
Phoebis philae. Orange-barred Sulphur. One seen by Dan and Ahmet in flight.
Phoebis argante. Apricot Sulphur. At least one on hotel grounds in flight.
Phoebis agarithe. Large Orange Sulphur. One landed on wet ground on hotel grounds, right after we got tested for Covid.
