Citron-headed Yellow-Finch

Small, retiring quail of forest understory. Rarely seen, but can be located by listening for noisy rustling in the leaf litter as birds scratch like chickens. Prefers to run away rather than flush. Loud song often reveals its presence, given mainly early and late in the day: first few notes similar to Little Tinamou song, but then breaks into rollicking choruses that can be almost deafening if close by. Male has rusty face and gray body, female colors reversed, with gray face and rusty body.

Pale, medium-sized gull, smaller and daintier than Glaucous or Herring Gulls. Often looks cute with rounded head and small bill. Extremely variable plumage. Variation is apparently clinal across the Arctic breeding range, from darkest in the west to palest in the east. The palest adults have very pale gray backs and nearly pure white wingtips. The darkest birds, formerly known as Thayer’s Gull, are darker gray above and have blackish wingtips. Young birds range from almost pure white to medium brown, never as dark as Herring Gull. First-year birds usually have a mostly dark bill. Winters along both coasts of North America and in Europe, often near the ocean or on large lakes. Typically found in small numbers among flocks of other large gulls.

Distinctive black-and-white banded owl with black eyes, a yellow bill, and yellow legs. Found in humid forests including Araucaria forests and occasionally in plantations and urban parks. The voice is a low, deep series of “uou” notes.
