The yellow-throated warbler (Dendroica dominica) is the most common member of the genus Dendroica in the southern United States, where it is known for being a harbinger of spring (2). It is aptly named for its brilliant plumage, with the bright yellow throat and breast, along with the white patch on the side of the neck, distinguishing this largely blue-grey bird from similar species. Other characteristics of the yellow-throated warbler include a white belly, two white bars on the wing, black streaks along the side, a long black bill and brown legs and feet (3).
The male and female yellow-throated warbler are difficult to distinguish, although the female is often duller (2). The spring adult male has the most vibrant colouration, just before it moults (4). The juvenile has an olive-brown head, and the body has brown, grey and white spots, as well as white wingbars (3).
The yellow-throated warbler is rather variable across its large range. A subspecies native to the Bahamas, Dendroica dominica flavescens, has an especially long, partially curved bill, an extensive yellow belly, and less obvious white patches (3). However, this subspecies is now considered to be a separate species, the Bahama warbler (Dendroica flavescens) (5). The yellow-throated warbler is similar to Grace’s warbler (Dendroica graciae), although this relative lacks white patches on the neck (3).
