Well, this tour got in and out of Mexico just before all heck broke loose worldwide, and I’m sure everyone was glad it was timed when it was! Happily unaware of what was about to befall us, we enjoyed a week of great birding, good food, some culture, and fine company! Oaxaca is one of those destinations that really could use better marketing in the US, as it is a fantastic place for all sorts of activities, birding not least among them. Our tour was quite a success in this regard, netting nearly 200 species and giving us great views of a number of Mexican endemics and many local and hard-to-see species.

We started on the Teotitlan road, which gave us a nice cross section of the various habitats available to us in the Oaxaca valley, from the dry floor, with its agricultural fields and scrubby patches, to the reservoir Presa Piedra Azul, in effect an oasis where we had a nice glut of waterbirds and others, up to the pine-oak forest on the ridge above. The next day, we visited the enchanting pine-oak forests on Cerro San Felipe, with the cool shade and impressive bromeliad loads on the branches. Our third day was quite a change as we visited the unique tropical thorn scrub at KM 77, on the Pacific Slope to the east of the Oaxaca valley. What a cool place, and we managed some great birds there! Then back to visit the Zapotec and Mixtec ruins at Mitla and Yagul, and to see the process to make mescal the traditional way. On day four we visited the impressive Zapotec ruins of Monte Alban in the morning and then headed up to Cerro San Felipe for an evening of birding, especially owling! Day five found us back on the Teotitlan road followed by a visit to a home-style restaurant and a wool dying and weaving workshop in town. Our final day we spent on the Yuvila side of La Cumbre in more oak-dominated pine-oak forest. Of course, we also enjoyed a bit of the city, including our lovely hotel and an evening on the Zocalo as we had a fine meal and listened to the crowd and music below us.

Highlights of these outings included (in order of their popularity): the glowing Orange-breasted Bunting at KM 77 that just lit up the tree, the similarly incandescent Red Warbler that was such an eye-catcher in the pine-oak forests in the mountains, the snazzy Russet-crowned Motmot, also at KM 77, as it eyed us and swung its tail like a pendulum, the Lesser Roadrunner that Jorge spotted and we managed to call into view by the vans at KM 77, the “cute” Northern Pygmy-Owls we had at several spots that acted as scapegoats, grabbing the attention of local small birds, the elegant Gray Silky-flycatchers that gathered in groups in treetops and chirped, as that huge flock did at Pollo Nino! The yelping Fulvous Owl on Cerro San Felipe was a favorite because… well… owls! The flashy Red-headed Tanagers that we enjoyed at Pollo Nino, and were a lifer for most, including Micah. Oaxaca Sparrows, as usual, played hard to get, but we eventually got everyone a good view, but the ornately patterned Bridled Sparrows were a bit easier to see. The yellow eyebrow of the Golden-browed Warblers stood out in the dim lighting of their preferred shady habitat on Cerro San Felipe. Our owling night finished up with a very nice view of a Whiskered Screech-Owl that came in close to check us out. The ethereal song of Brown-backed Solitaire cascaded around us at several spots, but none as much as at Yuvila, where it was one of the dominant birds! An unusually extroverted Cordilleran Flycatcher at Jilguero gave us an eyeful, as did several flashy Mountain Trogons at Yuvila, among other places. The personable Yellow-eyed Juncos in the openings of the montane forests also got on the list. And certainly not least: Teri found what may well be a new species of Euphorb while on the tour! That’s pretty darned exciting!

Our local crew, both Jorge and Ricardo, did a fine job of transporting us around, and Jorge guided us at the various ruins with his informative exposition of the history and culture of the region. We thank them both for their hard work! Micah and I also thank you all for joining us on this tour, and we hope you enjoyed it as much as we did (and more so now that travel is curtailed for the time being!). We hope that we will see you all again out there with binoculars on, and as you shelter in place, don’t forget that birding is a great way to keep yourself engaged in the world around you and perhaps a little less stressed from the current events!

Que nos pasamos esta epoca de dificultad y volvemos a pajarear pronto! (May we get through this challenging period and return to birding together soon!)

Guide Micah Riegner could barely keep steady enough to get this fine photo of this male Red-headed Tanager at Pollo Niño--it was a long-awaited lifer for him!

ORANGE-BREASTED BUNTING (Passerina leclancherii) – This rainbow of color showed well at KM 77 right off the bat! [E]
VARIED BUNTING (Passerina versicolor) – A male showed well at KM 77.

MEXICAN GRAY SQUIRREL (Sciurus aureogaster) – Common at the hotel, but a few in the mountain forests, too.
WHITE-NOSED COATI (Nasua narica) – We found a rather dead individual on the track at KM 77.
WHITE-TAILED DEER (Odocoileus virginianus) – Joan got us on this one.


Mexican Mud Turtle (Kinosternon integrum): in Presa Piedra Azul.

Spiny-tailed Iguana (Ctenosaura sp.): up the slope from the KM 77 canyon.

Scaled Lizard sp. (Sceloparus sp.): we probably saw several species in this genus, as they are numerous and speciose in the Oaxaca area.

Totals for the tour: 197 bird taxa and 3 mammal taxa
