The Gray-crowned Yellowthroat is normally found from northern Mexico southward through Panama. In the United States they are a vagrant, albeit with a number of sightings in far southern Texas near the Rio Grande river valley. The species was recorded as nesting in the United States in the late 1800s, and was even considered a relatively common breeder in a few counties along the Rio Grande. However, by 1920s they had seemingly disappeared. While occasional sightings occurred after that, it wasn't until 2005 that nesting in the U.S. was again confirmed, when a nest was found in Cameron County, Texas. Given the proximity to known nesting locations in northeastern Mexico, continued sightings in far southern Texas, and the potential impacts of a warming climate on the species' distribution, further breeding within the U.S. is considered likely.
Habitat
Found in shrubby, open habitats. This may include tall grasses with scattered shrubs, brushy thickets, young second-growth in forest clear-cuts, and brushy forest clearings.
Diet
Feeds mostly on insects and spiders. They will also sometimes feed on seeds or berries.
Behavior
Most foraging occurs while clambering and flitting through thick brush and thickets. Insects and spiders are gleaned directly from vegetation, although sometimes they will make short flights to capture flying insects in mid-air.
Nesting
The nest is a small cup built of grasses and leaves, usually placed in a thick clump of tall grass. The female usually lays between 2 and 4 eggs, and she alone incubates them. The eggs typically hatch after 10 to 12 days.
Song
The most commonly heard vocalization is a somewhat low-pitched chee-dle chee-dle chee-dle
Migration
Considered a permanent resident throughout their normal range.
