Genus Oporornis

Connecticut Warbler - These 15 cm long birds have light yellow underparts and olive upperparts; they have a light eye ring, pink legs, a long tail, pale wing bars and a thin pointed bill. Males have a grey hood; female and immatures are more brown and have a whitish throat.

Kentucky Warbler - Adult Kentucky Warblers are about 13 cm in length. They are mostly an olive-green in color on their back and nape, and a brilliant yellow below from their throat to their belly. They have a small tinge of black on their crown, and a large black mask with a yellow pattern that runs from the beak and encircles the eyes, resembling a pair of spectacles. Female Kentucky warblers have slightly less black on the sides of their head, and immature birds may have almost no black at all.

Mourning Warbler - The Mourning Warbler, Oporornis philadelphia, is a small songbird of the New World warbler family.

Macgillivray's Warbler - The MacGillivray's Warbler was named by John James Audubon in honor of Scottish ornithologist William MacGillivray, although the proper credit to its discovery goes to John Kirk Townsend. The scientific name "tolmiei" was given in honor of William Fraser Tolmie.
