Sao Tome Weaver

Ploceus sanctithomae

A medium-sized weaver with white wingbars, endemic to São Tomé. Sexes look quite different:  the male has olive-brown upperparts and a burnt-orange face and upper breast, while the female is more washed-out dull brown above and buff-white below. Found in pairs and small to large flocks that forage by themselves or with other species in any environment with trees, where they feed like nuthatches by clinging to branches and probing leaves, holes, and epiphytes in search of food. The warbler-like song starts with 4–5 clear high-pitched “steeeut” notes before accelerating into a strident trill; a common call is a sharp “chwet.” Other weavers on São Tomé lack wing bars.

Santa Marta Parakeet

Santa Marta Parakeet

Pyrrhura viridicata

Long tailed and rather plain parakeet endemic to Colombia’s Santa Marta Mountains. The thick, white eye ring and red blotches on face and breast are its best features. Blue and red in wings is mostly concealed with the bird is perched. Typically encountered in small flocks that fly from tree to tree in the cloud forest, screeching loudly. Regularly seen along the San Lorenzo Ridge in El Dorado Nature Reserve, where nest boxes have been placed to improve its breeding success. Also nests and roosts in dead palm trees.

Red-headed Bluebill

Red-headed Bluebill

Spermophaga ruficapilla

Pretty member of the waxbill family that has a massive, conical bill. Males have a black belly and females a spotted one, and both sexes show an all-red head. Found in rainforest, gallery forest, thickets, and secondary habitats. Usually in pairs or small groups, in areas with thick undergrowth, and usually some grass. Sometimes on roads and paths. Vocalizations include a quiet “schpit” call and a rarely-heard whistled song. Similar to Grant’s Bluebill, but separated by all-red head. Male similar to male Black-bellied Seedcracker, but separated by its black tail and its red-and-blue rather than all-blue bill.

Vega Gull

Vega Gull

Larus vegae

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.
