Black-throated Green Warbler Dendroica virens

Order: Passeriformes — Family: Parulidae


Its olive, black, white and golden-yellow plumage blends well with the light and shadows of the leaves in which it lives. The upperparts are olive green, and the underparts are white but with black streaks on the flanks. In all plumages, the face is bright yellow and there are two white wing bars. The male has an extensively black throat; the female and immatures are more subdued, with less black on the underparts.


Its songs consist of a very high-pitched, fast ‘zee-zee-zee-zoo-zee’ and a buzzy ‘trees-trees-murmuring-trees’. Both songs are easy to recognize, but locating the singer can be very difficult.




Migrates across the Gulf of Mexico. Winters in the southern Rio Grande Valley of Texas, the West Indies, Mexico and Central America. Spring movement is spread over March, April and May, fall's is late August to late October.


A bird of the forest, it can be seen in wooded areas of any type.


Its primary summer food is caterpillars, though it also eats other insects and spiders. In migration berries are a diet staple.
