Chestnut-cheeked Starling

Small, short-billed, warbler-like sunbird. The distinctive male has a blue bib. The female is drab but can be identified by its small pale eyebrow, greenish back, and overall size and shape. Found in forest at low elevation, mostly close to the coast. Often in forest understory; less conspicuous than a typical sunbird. Most distinctive vocalization is a rapidly repeated “tchew”. Shape, size, and olive-green back separate Plain-backed from other sunbirds.

A small, terrestrial wren of lowland and foothill rainforest. It is brown with a big white stripe on each wing and a gray throat and breast. In the eastern part of its range, birds are also finely scaled underneath. Wing stripe may be reduced or lacking on juveniles. Typically found alone, scurrying along the forest floor but occasionally perching a bit higher to perform its memorable song, a fast-paced series of clear, ringing whistles.

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.
