Sand-colored Nighthawk

Large brown duck with distinctive pale orange face, dark crown, and partial dark eyeline. Uses a wide range of lowland freshwater and brackish wetland habitats, including marshes, ponds, riverbanks, and mangroves. No similar large ducks regularly occur in its range. Usually in small flocks but may join wintering flocks of wigeons,shovelers, or other dabbling ducks.

A plain, sparrow-sized honeyeater with a slender, downcurved bill like a sunbird’s. Entirely rich olive above, plain gray on face and throat, with a yellow wash on the underparts. Restricted to the islands of Lombok, Sumbawa, and Flores. Plainer than Indonesian Honeyeater, lacking that species’ prominent pale facial skin, yellow wing panel, and a dark mask. Sunda is also noticeably more yellow underneath. Calls include a constant twittering, a nasal “jeez,” and a guttural “grrt.”

Brilliantly colored small partridge of montane and foothill forests. Often difficult to see in the gloom and tangle of shaded vegetation, but note slate-gray back and chest, rusty belly, and bright orange-and-black face pattern. Like other Arborophila partridges, typically forages on the forest floor in small groups. Song is a fast and gradually rising series of “whew” notes; when duetting, one bird gives the aforementioned song while its partner gives a slower, lower-pitched “boo-goo, boo-goo, boo-goo.”
