The summer male Myrtle Warbler has a slate blue back, and yellow crown, rump and flank patch. It has white tail patches, and the breast is streaked black. The female has a similar pattern, but the back is brown as are the breast streaks. The Myrtle can be distinguished from Audubon’s Warbler by its whitish eyestripe, white (not yellow) throat, and contrasting cheek patch.
Habitat and Distribution
The Myrtle Warbler has a northerly and easterly distribution. Its breeding habitat is a variety of coniferous and mixed woodland in much of Canada and the northeastern USA. It is migratory, wintering in the southeastern United States, eastern Central America, and the Caribbean. It is a rare vagrant to western Europe, and has wintered in Great Britain.
These birds are insectivorous, but will readily take wax-myrtle berries in winter. They have a habit of making short flights from their perch in search of bugs.
Myrtle Warblers nest in a tree, laying 4 to 5 eggs in a cup nest.
Calls and Songs
Their call is a hard check. The songs are trill-like, nearly indistinguishable, consisting of a 3 to 4 syllable tyew-tyew-tyew-tyew, sometimes followed by 3 more tew’s.
