Yellow-browed Tit

A large, sturdy gull of East Asia. Adults have a fairly pale gray back, pale eye, and dull pinkish legs. Takes four years for immatures to progress from mostly brown to fully white and gray adult plumage; intermediate plumages are often mottled and messy. Extremely variable plumage can make identification tricky. Occurs inland and along the coast, frequenting river mouths, harbors, beaches, lakes, and ponds. Often forms flocks with other gulls. Back color of adults generally a shade darker than that of American Herring Gull. Very similar to Mongolian Gull, and separation is tricky, but has a larger head and bill; adults also generally have pinker legs.

Huge black vanga with a rufous back and an enormous blue bill. Rare and localized Madagascar endemic that is found in northeastern rainforest at low and middle elevations. Usually in the mid-story, perching motionless for long periods. Often joins flocks with other large vangas. Most easily located when nesting in a large mossy cup that is placed on a forking mid-story branch. Song is a long, delicate, high-pitched, slightly descending trill. 

Stocky canopy dweller with a stout bill and striking plumage. The male has black upperparts, a broad black mask with a white crown and throat, a yellow wash on the breast, black streaks on the sides, and a tuft of reddish-orange feathers sticking out from under the wing. The female is similar but with an entirely black head and breast. Occurs in the canopy of lowland forest from central Panama into western Colombia. Usually in pairs or small groups.
