White-bibbed Antbird

Smallest gull in the world. Compact with short legs, short rounded wings, and small bill. Breeding adults have black head, pale gray back, white wingtips, and blackish underwings. Nonbreeding adults have a black ear patch and smudgy cap. Immatures are similar to nonbreeding adults but with a black “M”-shaped pattern on the upperwing, especially noticeable in flight. When perched, this looks like a thick horizontal stripe across the wing and shoulder. Primarily a Eurasian species, breeding in marshy wetlands and wintering offshore or in coastal waters. Uncommon to rare in North America, where typically found singly among flocks of Bonaparte’s Gulls on lakes, beaches, estuaries, or bays. Note adult Little Gull's smaller size, white wingtips, dark underwings, and more rounded wings compared to Bonaparte's.

A stunning antshrike, fairly common in open woodland and scrub in northern South America. Male has black head with white hind collar, white belly, brown back, and obvious white spotting on wing. Female is buffy overall with black tail, rufous crown, and buffy wingbars. Both sexes have a bushy crest, which is usually obvious. Some geographic variation across range: males in northern Colombia have grizzled white speckling on face; males in southern Venezuela and northern Brazil are much darker overall. Typically seen in pairs moving through the lower and middle levels; not particularly skulky.

A sleek forest bird that sometimes ventures into gardens and parks in search of flowers and fruit; prefers areas with palms. The adult is distinctive—clothed in black except for patches of yellow on lower belly, shoulders, and rump. No similar species occur within its range. Immatures are muddled yellow, orange, and olive, developing adult plumage over the course of a year. This plumage resembles that of female and young Baltimore Orioles, a scarce migrant and winter visitor to Hispaniola. Similarly attired Baltimore Orioles can be distinguished by their orange underparts and white wingbars. The song is a rapid jumble of squeaky and metallic notes. Calls include a buzzy “jrrrt” and a metallic “zhwee.”
