Yellowthroat warbler are surprisely common than most people think. They are often heard rather than seen.
They absolute loves any kind of wetland. They will live in shrubs, woodland edges, and grassland near water edge as long as they have a "shrub" for a nesting space that escape most predator notice.
One of the few nesting Eastern Temperature United State species (thought they also breed in the Western United States). Most of the warbler species that usually are seen in the Eastern United States usually prefer to breed in boreal or south east US.
They are heavily parasitized by Cowbirds because of their timid nature and their nests is somewhat easier to find than some other bird species (by Cowbird standard).
