Black-Throated Blue Warbler: Art and Information


Illustration by Gabriel Ricketts


Identification: The Black-throated Blue Warbler (Setophaga caerulescens) is a small member of the family Parulidae or wood-warblers. The males are a brilliant deep blue above with a black face and throat, and a single, wide black stripe going down the side. Females are brownish below, and greenish brown above with a pale eye-ring and a pale eye-line. Males and females look so different that at one point they were described as different species. But the one feature of the Black-throated Blue Warbler that both males and females of all ages share is a white spot, commonly referred to as a handkerchief, on the wing close to the side. The song of the Black-throated Blue Warbler is a rather slow and lazy series of long buzzes and sometimes a clearer note. One in particular literally sounds like the bird is saying “sooo-laaa-zzzyyyy”.


Habitat: Black-throated Blue Warblers inhabit a variety of different habitats but prefer woodland undergrowth. They breed in mixed evergreen-deciduous woodlands with a thick understory of shrubs including Mountain-Laurel, Rhododendron, and Hobblebush. In migration they can be found almost anywhere with a few trees and some bushes underneath. Black-throated Blue Warblers breed throughout most of the Northeastern states and some of Southeastern Canada, as well as the Appalachian Mountains at elevations of 2,600-5,250 feet. Black-throated Blue Warblers show up in our area around late April and persist in good numbers until early June when they head up into the mountains to breed. They head south to their wintering grounds by late October.
