Inca Dove

Cryptic nightbird, more often heard than seen. Listen for namesake song, a whistled "whip-poor-WILL," repeated endlessly. Rolling and more trilled than Eastern Whip-poor-will song. Found in forests in foothills and canyons, often with a mixture of pines and deciduous trees, and open areas nearby for foraging. Forages at night from the ground for flying insects. Intricately patterned with gray, brown, and black. Similar to Common Poorwill but with longer tail, different voice, and different habitat. Eastern and Mexican Whip-poor-wills were recently split into separate species; they differ mainly in voice and do not overlap in range.

Odd, slender antbird with a rather long bill. Males are gray above and white below with white spots on the wings; females have rusty underparts and lack wing spots. Found across a restricted range in the understory of stunted campina forests. Does not generally associate with mixed-species flocks, but may sometimes attend army-ant swarms. The song is a series of harsh notes with short “pips” in between: “grrrrrrr-pipip-grrrrrrrr-pip.”

Medium-sized plover with a pale throat, brown back, and white belly. Breeding adults have a black mask, white forehead, and a bright orange chest and neck; males average brighter than females. Non-breeding and immature birds are brownish above and white below, with a variable white forehead and eyebrow. Compare with slightly larger Greater Sand-Plover; Siberian is proportionally smaller-headed and darker-legged, and its shorter bill has a slight bulge at the tip. Smaller Kentish Plover can be similar in non-breeding plumage; Siberian is taller and longer-legged, without Kentish’s strong white neck band. Very difficult to distinguish from Tibetan Sand-Plover, especially nonbreeding and immature birds, though identification can often be presumed by range. In breeding plumage, note the less extensive black mask of Siberian, usually with a white spot on the forehead. In nonbreeding plumage, look for a generally stronger breast band and faint brown markings on the flanks in Siberian. In areas of overlap many birds best left unidentified. Breeds mainly in Russian Far East; winters on coastal mudflats and beaches from Taiwan to Australia.
