The Crescent-chested Warbler is found in parts of Mexico and Central America, but was unknown in the United States until 1983, when a bird was confirmed at Fort Huachuca in southern Arizona. Another was found in southern Arizona the next year, and sporadic reports have occasionally occurred since then. A handful of records have now also been recorded near the Rio Grande in Texas.
Habitat
Found in oak/pine and mixed forests in the core of their range in Mexico and Central America.
Diet
Feeds on insects
Behavior
Despite nests being located on or near the ground, foraging is typically done by moving through the forest canopy, gleaning insects from foliage and branches. They sometimes hang upside down while foraging, similar to the manner of a chickadee.
Nesting
The nest is a cup built either very low in vegetation or on the ground, usually placed on a steep slope. The female lays between 2 and 4 eggs and she alone incubates them. Both parents help to feed the young once they hatch.
Song
Song is a repeated, buzzy k-k-k-k-k-k
Migration
Considered a permanent resident throughout their range, although movements to lower elevations in winter are noted for many birds in montane environments.
