Swainson's Warbler

This is a heavier crop that I usually employ, but hell, it's headshot of a Swainson's Warbler. They aren't as colorful as many of their wood-warbler relatives, but I took special satisfaction in capturing this image because the bird is among the stealthiest members of family Paruidae. The large beak distinguishes this species, so its fun to see it so well in this close view.
