Hume's Wheatear

A medium-sized duck, similar to female Mallard in appearance, but smaller and darker. Males lack the green head and curled black tail feathers of male Mallards. Both sexes have spotted tail feathers. The bill is dark greenish, with an orange tip in some females. Pure Hawaiian Ducks occur only on Kauai and montane streams and ponds on Hawaii Island. Most or all individuals on other islands are Mallard-Hawaiian Duck hybrids. Occurs in ponds, marshes, taro fields, and streams.

Big, spectacular, black-and-white hornbill. Both sexes show a pale bill, with a large casque that is larger in males and smaller in females. In flight, the wings are mostly black with a small white patch below, and there are white corners to the tail. Found from low to high elevations in forest, and adjacent areas of lush woodland and cultivation. Usually in pairs or small groups. The loud calls are honking and yapping notes that are often given in a quick series. Similar to Black-and-white-casqued Hornbill, but has a paler bill, and much less white in the wings. Also reminiscent of Trumpeter Hornbill, but larger, with a bigger bill, and less white in the wings and on the belly.

Tiny, round quail of lowland plains, grassy hillsides, and farmland. Generally uncommon and often glimpsed only briefly as it flushes from almost underfoot. Male gorgeously attired, with a blue head and breast, deep cinnamon belly, and neat black-and-white throat markings. Female brown with a paler belly and a plain face; compare to the strong white brow of the larger Japanese Quail. Males give a descending, plaintive whistle, “tew-tew”, and a raspy, snoring call.
