It is 12 cm (4.7 in) long and weighs 9 g (0.32 oz), and has an olive-green crown, a yellow face with olive markings, a thin pointed bill, white wing bars, an olive-green back and pale underparts with black streaks on the flanks. Adult males have a black throat and upper breast; females have a pale throat and black markings on their breast.
The breeding habitat of the black-throated green warbler is coniferous and mixed forests in eastern North America and western Canada and cypress swamps on the southern Atlantic coast. These birds' nests are open cups, which are usually situated close to the trunk of a tree.
These birds migrate to Mexico, Central America, the West Indies and southern Florida. One destination is to the Petenes mangroves of the Yucatán. Some birds straggle as far as South America, with the southernmost couple of records coming from Ecuador.

This bird is vulnerable to nest parasitism by the brown-headed cowbird.
