Range and Habitat
Crescent-chested Warbler: Resident of montaine oak-pine and mixed softwood forests of Mexico to Central America. Seasonal migration to lower elevations within mountain ranges has been documented. Very few records in the United States from southeastern Arizona and in the lower Rio Grande Valley, Texas.
The Crescent-chested Warbler jumps from twigs and foliage, picking food from the underside of leaves, and hanging beneath leaves in a fashion similar to chickadees to check surfaces for prey.
A group of warblers has many collective nouns, including a "bouquet", "confusion", "fall", and "wrench" of warblers.
The Crescent-chested Warbler has a large range, estimated globally at 400,000 square kilometers. It is native to Mexico, United States, Nicaragua, Honduras, Guatemala, and El Salvador and prefers moist subtropical and tropical forest ecosystems. The global population of this bird is not exactly known, but because the population is described as frequent it does not appear to meet population decline criteria that would necessitate inclusion on the IUCN Red List. The current evaluation status of the Crescent-chested Warbler is Least Concern.
