Setophaga graciae

Tiny8 gForest

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.
