Annobon White-eye

A medium-sized swift-like bird with long tail-streamers. Adult has a dark greenish-blue crest visible while it perches, mostly on trees. It has uniform pale gray upperparts, black lores with a fine white border above, and much rufous on the face of the male. Underwing feathers, breast, and flanks are pale gray, and belly is whitish. Female has a dark mask, replacing the male’s rufous coloration. The species is partial to lightly wooded country, avoiding open plains and wet forests. Mostly seen on the wing, and at times perched, making a characteristic “gek-kuk” call.

Large owl with prominent facial disc and very powerful legs. Nests in a variety of habitats; requires hollows of very large trees for nest sites, and these may be in both drier and wetter forest types. Variable in size and color, ranging from larger, browner birds in Tasmania through to smaller, paler birds in northwestern Australia. This species is generally larger, darker, larger-legged, and more heavily spotted than Barn Owl. Call includes a loud explosive hiss.

A typical forktail, with piebald plumage and long tail. Black head, upper back, chest and wings; white belly, rump, forecrown and wingbar; black and white tail and pale-pink legs. Inhabits shaded whitewater streams through montane rainforests, along which it perches on boulders and low-hanging branches. May overlap at mid-elevations with the very similar White-crowned Forktail which occurs in the lowlands, but Bornean has a longer tail and less extensive white on the head. Often detected by its vocalizations, a harsh buzzing whistle and high metallic whistles.
