Azure-shouldered Tanager

This heavily marked thrush is easily identified when seen well. Females average duller than males, but both sexes have a dark cheek on an overall white face, brown upperparts (strongly rufous-tinted in males), bright rufous wings, and dark underparts densely marked with white chevrons. Much darker than scarce Naumann's Thrush, with which it may associate and sometimes hybridizes. Very vocal, delivering loud chattering notes in both songs and calls. Breeds in taiga, tundra, and steppelands; winters in forests, as well as open habitat such as forest edges and fields.

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.

Well-attired small songbird typically associated with mid- to high-elevation farms, fields, and open forests throughout its range. Found in less intensively developed areas than House and Eurasian Tree Sparrows, sticking to villages and pastures and staying away from large city centers. Male has bright chestnut cap and back, whitish cheek, narrow black throat, and pale gray belly. Female brownish with broad streaks above, pale below, with white wingbars and broad tan supercilium.
