Rote Boobook

Ninox rotiensis

Found only in forested areas on Rote Island, this medium-sized brown owl is physically all but identical to several closely-related species spread out across Indonesia and Australasia; fortunately, no others are present on Rote. Note the bright yellow eyes, speckled underparts, and large round head characteristic of the Boobooks. Gives a very dry, grating “grukgruk”, often in extended series and in duets. Formerly regarded as a subspecies of Southern Boobook.

识别特征

The Rote boobook (Ninox rotiensis) is a species of owl in the family Strigidae. It is endemic to Rote Island in the Lesser Sunda Islands of Indonesia. It was first described in 1997 by Australian biologists Ronald Johnstone and J.C. Darnell from a female collected in a mist net in 1990. It is smaller than the Australian boobook, with heavily barred primaries, rump and tail. Locally common, it is known as Tuterui and Kokorok in Landu and Oelaba localities respectively on the island. Genetic and call analysis show it to be markedly divergent from the Australian populations of the Australian boobook, leading Gwee and colleagues to suggest it be reclassified as a separate species, which duly happened in 2019.

Black Woodpecker

Black Woodpecker

Dryocopus martius

Unmistakable large, crow-sized woodpecker, all black with a red crown, which is reduced in females. Powerful, straight, and rather flappy flight without the undulations of other woodpeckers. Very noisy, with a strident "ke-yaa" given when landing or perched and a "krry-krry-krry" call uttered in flight. Found in a range of forest types, especially older mixed forest.

Tui

Tui

Prosthemadera novaeseelandiae

A large, dark nectar feeder endemic to New Zealand. Easily distinguished by two curled white feather tufts (“poi”) visible on the throat. Tail and wings have blue, purple, and green iridescence. Found throughout much of New Zealand, including Auckland, Kermadec, and Chatham Islands, though mostly absent from Canterbury. Favors native forest and scrub, also venturing into suburban parks, farmland, and rural gardens. Often detected by its unique voice consisting of melodious notes intermixed with croaks, coughs, clicks, and wheezes. Also listen for its noisy whirring flight. Similar to male Eurasian Blackbird, but easily identified by its white throat feathers and iridescence. Song can be easily confused with that of a bellbird, but listen for distinct loud coughs, grunts, and wheezes in Tui song.

Deep-blue Flowerpiercer

Deep-blue Flowerpiercer

Diglossa glauca

A small tanager with navy blue plumage, a brilliant golden eye, and a hooked bill. It ranges in cloud forest along the east slope of the Andes and at lower elevations than other flowerpiercers (none of which have a golden eye). It is less dependent on nectar than other flowerpiercers, consuming mostly insects and berries. Frequently joins mixed-species flocks.
