Moluccan Owlet-nightjar

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.

A slim brown buzzard with a distinct white iris. Adults have a white throat with a prominent dark stripe, yellow base of the bill, and rufous tail. Dark tips to wing feathers are clearly visible in flight. Often shows a white patch on its nape. Juveniles have a buffy head and brown iris. The usual habitat is dry, open country or forest, where it mainly feed on insects, rodents, and small mammals. This species is most often seen soaring alone in thermals or perched still. Groups of two or three may sometimes be seen. The most commonly heard call is a plaintive mewing note or falling whistle. 

Not closely related to Northern Mockingbird. Skulking and heard far more often than seen, this fairly large and ample-tailed songbird might be better named "denim catbird" for its overall dull blue plumage, mewing calls, and retiring behavior. Favors thickets, dense scrubby woodlands, and forest understory in foothills and highlands; locally to western lowlands in winter. Tosses leaves on the ground and also feeds at all levels in dense fruiting bushes and trees. Most often seen in short flights across roads or trails from cover to cover. Voice notably varied.
