Lucy's Warbler
Leiothlypis luciae
Lucy's warbler is the smallest species of New World warbler. It measures from 9 to 12 cm (3.5 to 4.7 in) in length and can weigh from 5.1 to 7.9 g (0.18 to 0.28 oz), thus being slightly smaller even than the warblers formerly placed in the genus Parula. Among standard measurements, the wing chord is 49 to 61 mm (1.9 to 2.4 in), the tail is 33 to 41 mm (1.3 to 1.6 in), the bill is 7.8 to 9 mm (0.31 to 0.35 in) and the tarsus is 15 to 17.5 mm (0.59 to 0.69 in). It is rather undistinguished compared to other wood-warblers, being perhaps the palest species in its family.

Virginia's Warbler
Leiothlypis virginiae
Virginia's warbler is a small bird, only 4 to 4+1⁄2 inches (100 to 110 mm) in length. It is mainly gray in color, with a lighter colored under-belly and a white eye ring. The rump and undertail coverts are yellow. They also have a yellow patch on their breast and a partially hidden dark reddish crest. Females are slightly duller, with less yellow on breast. Virginia's warbler can be easily mistaken for the rare Colima warbler, but it is smaller, has a more yellow rump, and is more widespread. Colima Warbler also lacks yellow breast patch.
