| Dendroica dominica (Linnaeus, 1766) |
The Yellow-throated Warbler, Dendroica dominica, is a small New World warbler. These birds breed in southeastern North America, and their breeding ranges extend from southern Pennsylvania and northern Missouri, to the Gulf of Mexico.
Two subspecies may be found in northwest Florida and the Bahamas. These are resident in those locales, but the other populations of these birds are migratory, wintering at the Gulf Coast, eastern Central America, and the Caribbean. Vagrant wintering birds are sometimes seen in northenmost South America[1].
In summer, male Yellow-throated Warblers display grey upperparts and wings, and also boast of double white wing bars. Their throats are yellow, and the remainder of their underparts are white, and are streaked with black on the flanks. Their heads are strongly patterned in black and white, with a long white supercilium; the different subspecies may display yellow and white superciliums.
Other plumages of these birds resemble washed-out versions of the summer male, and in particular, lack the strong head pattern. This other plumage also displays weaker yellows, with grey feathers replacing black ones.[verification needed]
Their songs are clear, descending whistles. Their calls are high sees or sharp chips.
The Yellow-throated Warbler is a woodland species with a preference for coniferous or swamp tree species in which to nest. They are insectivorous, but will opt for berries and nectar in winter if no insects can be found.
These birds build cup-shaped nests which are built in a trees, and are concealed amongst pine needles or Spanish moss. Their clutches consist of 3-5 eggs. Four eggs is the usual amount, however.
