In winter, northerly-breeding populations migrate south, spending the winter anywhere from coastal California and the coastal southeastern U.S. south to Central America and the West Indies. Some southerly-breeding populations, particularly those in the tropics, are non-migratory. Blue-gray Gnatcatchers breed in a number of semi-open woodland habitats, particularly in habitats with deciduous trees and often in locations near water. In winter, this species utilizes a variety of tropical and subtropical shrub habitats. As this species’ name suggests, Blue-gray Gnatcatchers primarily eat small insects. In appropriate habitat, Blue-gray Gnatcatchers may be observed flitting through the undergrowth or the lo
