One of the most appropriately named warblers (it is rarely found away from pines), the pine has a drab plumage that makes identification challenging away from breeding areas. It is the only wood-warbler known to regularly feed on seeds, mainly in fall and winter. Between April and June, it builds a nest high in a pine on a horizontal limb, often at the end of a branch, and lays 3 to 5 eggs. Polytypic (4 ssp.; pinus and florida, not field identifiable, in North America). Length 5.3".

Adult male: olive green upperparts. Yellow throat, breast, and belly, extending to rear of olive cheeks; white lower belly and undertail coverts. Dull olive to blackish indistinct streaks on sides of breast. Indistinct
