About These Birds
Black-capped Gnatcatcher
The Black-capped Gnatcatcher is a tiny, active insectivore of tropical dry forest and thorn scrub in western Mexico, with males showing a bold black cap in breeding plumage and white underparts. It inhabits arid and semi-arid scrublands and dry deciduous forests from Sonora and Sinaloa south to Oaxaca. It feeds on tiny insects and spiders, flitting through dense low vegetation.
