Measurements:[2] 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, with preference for dense stands of conifers.

[3] 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.

Some birds straggle as far as South America, with the southernmost couple of records coming from Ecuador.
