Grace's Warbler
Setophaga graciae
Grace's warbler is a small bird, 11–13 cm long. It is mostly gray on top, with broken black streaks across the back and flanks and two white bars on the wings. The throat and breast are a vibrant yellow, and the rest of the underparts are white. It has a yellow half-eye ring under the eye and a long yellow "eyebrow" stripe that starts at the base of the beak and runs above the eye, fading to white after it passes the eye.

Hermit Warbler
Setophaga occidentalis
Hermit warblers are dark gray in coloration on top, and white below, and their flanks are streaked with black. The wings have two diagonal white wing bars. The majority of the hermit warbler's head is yellow, and males have a dark black throat, while females have much less black on their throat bib and immature birds have no black throat. Both males and females measure 5.5 inches (14 cm) in length, 0.3 to 0.5 oz (8.5 to 14.2 g) in weight, and 7.9 in (20 cm) in wingspan.
