Black Hawk-Eagle

Spizaetus tyrannus

Uncommon, spectacular, crested eagle of lowland tropical forest. Most frequently seen soaring in mid-late morning; rarely seen perched. Gives loud, far-carrying whistles while flying, which often indicate its presence. Adult is black overall with bold white checkering under the wings and bold white bands on the tail. Immatures, although rarely seen, are browner with a white throat and crown. The short bushy crest is usually apparent only on perched birds and is not seen in flight.

识别特征

The black hawk-eagle is 58–70 cm (23–28 in) long and weighs about 900–1,300 grams (2-2.9 lbs). It has black plumage with varying patterns on its wings and body, and white speckling in places. It has barred wings, slightly elliptical in shape, and a long, narrow tail which is rarely fanned. The four grey bars on the tail are distinctive to the black hawk-eagle, as is the white line seen slightly above the bird's eye. While flying, the broadness and shortness of the wings become apparent. While in flight, the bird's tail is typically kept closed.

行为

The black hawk-eagle is a solitary bird who only ever encounter each other during a territory feud or during mating season. When they hunt down prey they look briefly atop perches for anything and if they don't find anything they fly to another perch. Upon finding prey they are taken by pouncing or tail-chasing.

Pachycephala calliope

Medium-sized songbird, endemic to the Lesser Sundas and far eastern Java. Throughout much of range, the typical Golden-type Whistler: brightly-colored males have a striking black-and-white head and flashy yellow collar, breast, and belly, while considerably duller females are brownish overall with paler underparts, whitish throat, and yellow vent. Like other Pacycephala whistlers, a forest species, often seen gleaning insects from the foliage, or heard giving its loud, vibrant, rising song. Also gives a rising “weet” call.

White-chinned Jacamar

White-chinned Jacamar

Galbula tombacea

Similar to many other species of jacamar: mostly glittering emerald-green with a rufous belly, long tail, and long pointed bill. Sexes are similar; female has a paler belly. Found in northwestern Amazonia, where pairs occur in the lower to mid-levels of mature lowland forest, often around water. Namesake white chin is not super conspicuous but usually visible. Also note brownish crown. Most similar to Bluish-fronted Jacamar, but apparently no range overlap.

Cinderella Waxbill

Cinderella Waxbill

Glaucestrilda thomensis

Pretty little gray waxbill with a black tail and a red rump which is conspicuous in flight. The male has red and black under the tail, while the female is much paler and grayer below. Both sexes have pink in the bill. Found in arid woodland and savanna, including mopane woodland. Shy and inconspicuous; usually in small flocks. Calls include rising whistles. Very similar to Black-tailed Waxbill, but prefers drier habitat and is paler gray, with pink on the bill.
