orienteparula Teretistris fornsi

A noisy flocking species that uses a wide variety of wooded and scrubby habitats. Its combination of blue-gray upperparts, yellow from throat to upper belly, and gray lower belly eliminate all other species in range. The similar Yellow-headed Warbler has a yellow crown and a gray chest. The Prothonotary Warbler has a greenish or yellow crown and a green back. Calls include a relatively high and buzzy “zip” or “zhip” and a rather sharp, but slighty buzzy “tip”; both typically given in a somewhat rapid series. Song is a jumbled combination of these and similar notes.
