Today we’re in the state of Oaxaca, in southern Mexico. Winter here is a great time to visit old friends—birds, that is—we met in summer, back in the US.
The tops of flowering trees are “busy” with Yellow-rumped Warblers and Western Tanagers—northern nesters that winter in Mexico. These northerners get to mingle with Berylline Hummingbirds and Gray Silky-Flycatchers, year-round residents of the tropics.
Let’s leave Oaxaca City for the countryside, and ascend through a series of habitats. Here—where tall stands of cactus give way to shrubby oaks—another bird is escaping the northern winter, a neon-orange Bullock’s Oriole, perched in a morning-glory tree.
And, just below, is a Blue Mockingbird, a tropical gem found only in Mexico.
Ascending further, to 7000 feet, we’ve entered a misty forest of tropical oaks festooned with bromeliads. Wow! What a flock of warblers working that oak tree! Flashy Townsend’s Warblers and glowing yellow Hermit Warblers, foraging alongside the splendid Crescent-chested Warblers of the tropics.
And listen to that! It’s a Brown-backed Solitaire singing, a song that fills the Mexican forest as no other can.
