Colima Warbler

Basic Description

The understated, gray-brown Colima Warbler is a bird of Mexico's pine-oak woodlands. Both sexes flash a neat white eyering and brilliant yellow base of the tail as they search through foliage for insects and spiders. The female builds a cup nest on the ground under protective rocks or grasses. The species lives almost exclusively in Mexico, breeding high in the mountains of the Sierra Madre Oriental and migrating to the Pacific slope for the nonbreeding season. Its range barely reaches the U.S. in the Big Bend region of Texas.
