| Dendroica fusca (Müller, 1776) |
The Blackburnian Warbler, Dendroica fusca , is a small New World warbler. It breeds in eastern North America from southern Canada, the Great Lakes region and New England south to North Carolina.
It is migratory, wintering in the southern Central America and South America, and is a very rare vagrant to western Europe.
This species is 11.5 cm long and weighs 8.5 g. The summer male Blackburnian Warbler has a dark gray back and a double white wing bar, yellowish rump and dark brown crown. The underparts are white, tinged with yellow and streaked black. The head is strongly patterned in yellow and black, with an orange throat.
Other plumages are washed-out versions of the summer male, and in particular lack the strong head pattern, with weaker yellows and gray instead of black.
The breeding habitat is mature coniferous or mixed woodland, especially spruce and hemlocks. Blackburnian Warblers nest in a tree, laying 4-5 eggs in a cup nest.
These birds are insectivorous, but will take some berries in winter. They usually search for insects in the treetops.
The song is a simple series of high swi notes. The call is a high sip.
This bird was named after Anna Blackburne, an English botanist.
