White-fronted Ground-Tyrant

Small, entirely dark sooty-brown honeyeater. Very plain and lacking any colorful distinctive features. Found on the Indonesian island of Halmahera, as well as smaller adjacent islands. Uses forest and forest edge, in the lowlands and at moderate elevations. Similar to female Black Sunbird, but shows a more strongly downcurved bill, less contrast between the upperparts and underparts, and never shows the yellow tones on the belly usually shown by Black Sunbird.

Long-winged nightbird with intricate brown and gray patterning. Very similar to Common Nighthawk, best distinguished by voice. Gives a rapid series of hard, buzzy notes: "drik-rik-rik-rik." A Caribbean species; in the U.S., found only on the Florida Keys. Prefers open areas with mix of grass, bare ground, and shrubs. Nocturnal but can be seen hunting around dawn and dusk, searching for insects in flight.

Medium-sized plover with a pale throat, brown back, and white belly. Breeding adults have a black mask 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; Tibetan 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; Tibetan is taller and longer-legged, without Kentish’s strong white neck band. Very difficult to distinguish from Siberian Sand-Plover, especially nonbreeding and immature birds, though identification can often be presumed by range. In breeding plumage, note the more extensive black mask of Tibetan, typically lacking the white spot on the forehead of Siberian. In nonbreeding plumage, look for a generally broken breast band and clean white flanks in Tibetan. In areas of overlap many birds best left unidentified. Breeds on margins of high-elevation lakes and rivers in China and Mongolia; winters on coastal mudflats, beaches, and inland lakes from Africa to Indonesia.
