Black-throated Grey Warbler
Setophaga nigrescens
The black-throated gray warbler has mostly black, gray, and white plumage, which is soft, lacking gloss. With its striping and the small yellow spot between its eye and bill, it is a distinctive bird. The sexes differ slightly, both having gray upperparts with black streaks, and white underparts with black streaks on the flanks. The adult male is striped with black on the crown, throat, and below the eye, and has white around its chin and above its eye. The adult female has more dingy plumage on its head, with a white throat and dark gray cheeks.
