White-browed Ground-Tyrant

Unique and unmistakable inhabitant of the central and southern Ogasawara (Bonin) Islands. Gray-olive with a yellow head and strange triangular black mask. Found in a range of different habitats on the Ogasawaras, from remnant native vegetation to cultivated gardens. Feeds on the ground and at all levels of vegetation, often in pairs or small flocks. Gives sweet “deeeyu” and sharp metallic squeaks, amongst other vocalizations.

Small gray-brown minivet. Male has bright white face with a dark gray nape and a slender line through the eye. Female has a less contrasting facial pattern. Both sexes are gray above and buffy brownish-white below. Similar to Ashy Minivet, but note Brown-rumped’s brown rump and “stained” underparts. Brown-rumped is found in lowland and foothill wooded areas, often in flocks in winter. Often encountered flying overhead; listen for their bubbling metallic trills.

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.
