Giant Weaver

A small-bodied hornbill with an extremely long tail, a dark bill, and an almost entirely white head with a unique crest. Usually found in thick rainforest, where it can be difficult to view. At times, these birds will follow troops of monkeys to eat animals they scare out of the foliage. Vocalizations are unique among African hornbills, including crowlike caws and long mournful wails. Calls can be similar to those of Congo Serpent-Eagle, but White-crested Hornbill often gives more of a wail with a somewhat raspy quality.

Small, dull flycatcher. Medium brown with a light yellow belly, and two whitish wingbars. Breeds in dry scrub and open woodlands across much of southern South America; also a common austral migrant into Amazonia, where it is found in secondary and successional growth. Compared to the similar Amazonian Scrub-Flycatcher, Southern has a brighter yellow belly, and crisper, brighter white wingbars.

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.
