Tagula Shrikethrush

Colluricincla discolor

A chunky bird with a notably thick dark bill. Fairly nondescript: olive-brown on the upperparts and paler below. Found at low and middle elevations, in the understory and at middle levels of humid forest. Rich, melodious, variable song consists of whistles and rasping notes, often in an up-and-down pattern. Within its limited range, most likely to be confused with female Louisiade Whistler, but drabber overall, without yellow underparts.

分类信息

This species was formerly considered a conspecific member of the little shrikethrush complex. Genetic investigations of New Guinea populations of the little shrikethrush indicate high levels of genetic divergence, suggesting it comprised more than one species.

MacGregor's Bowerbird

MacGregor's Bowerbird

Amblyornis macgregoriae

The common and widespread bowerbird of montane forests. Fairly large, stocky brown like other closely-related species, but the male has a long, flowing, orange crest from the back of its head. The male builds a “Maypole” bower of sticks from a central pole and has a circular mossy arena at the base. Similar to the Streaked Bowerbird, but MacGregor's Bowerbird is found higher up and is larger and unstreaked. Call, a loud rasping. Various whistles and other sounds made at the bower, including mimicry.

Black-chinned Hummingbird

Black-chinned Hummingbird

Archilochus alexandri

Small hummingbird found in a variety of woodland and brushy habitats. Male distinctive with purple-and-black throat. Female has whitish underparts with almost no buffy tones (perhaps a very light wash on flanks). Tends to pump its tail more than other hummingbirds. Readily comes to sugar water feeders and flower gardens. Common in summer over much of the western U.S., barely into Canada. Winter range extends just south of Mexico City, and increasingly regular on the Gulf Coast of the U.S. Very difficult to distinguish from Ruby-throated Hummingbird, especially females and young males; thankfully limited range overlap. Black-chinned averages somewhat dingier green above, longer-billed with a slight droop, and has slightly broader, more club-shaped outer wing feathers, but these differences are all extremely subtle.

Dusky-cheeked Fig-Parrot

Dusky-cheeked Fig-Parrot

Nannopsittacus melanogenia

A small, short-tailed parrot of lowland forest and edge, mainly at low elevations. Green body with dark blue in the wing, and a dark forecrown and cheek. Males have a white line separating the cheek, crown and bill, and usually an orange chest. Female has a darker face, less orange on the breast, and an orange patch behind the dark cheek. Usually found in small groups. Most similar to Double-eyed Fig-Parrot, but Dusky-cheeked has blackish instead of red forecrown and cheek, and an orange breast. Calls a sharp, high-pitched “tsik!” or excited twittering which often betrays their presence in a tree.
