Riverside Wren

Cantorchilus semibadius

Medium-sized wren with rufous upperparts and bold black-and-white barred underparts. Complex black-and-white face pattern. Sexes alike. Found in pairs or small groups, foraging in the lower levels of forests and shrubby edges.

识别特征

The riverside wren is 13 to 14 cm (5.1 to 5.5 in) long and weighs 17 g (0.60 oz). The adults have a bright orange-brown crown; chestnut nape, back, and rump; and a blackish tail with buff-white bars. They have a black-over-white supercilium and the rest of the face is streaked and spotted black and white. From throat to vent their underparts are pale gray with narrow black bars; the gray becomes somewhat buffy to the rear. Juveniles are duller overall, have fine black scaling on the crown, and the underparts' black bars are not as crisp.

分类信息

The riverside wren has sometimes been treated as conspecific with bay wren (Cantorchilus nigricapillus) but their plumages are quite different as are DNA analyses. The species is monotypic.

Western Bearded-Greenbul

Western Bearded-Greenbul

Criniger barbatus

A big, chunky, relatively colorful rainforest greenbul. Mostly olive-green, with a reddish tail and a mostly gray head. The throat feathers are long and often puffed out; they are rich yellow in most of the range, but pale yellow in Nigeria. Found in the understory and at middle levels of rainforest and gallery forest. Usually in small, noisy groups that often join mixed flocks. Similar to Yellow-bearded Greenbul, but larger, with a puffier throat and some gray in the plumage. Similar to Red-tailed Greenbul, but larger, and never shows a pure white throat. Somewhat similar to Icterine Greenbul, but larger, and much darker on the breast and belly. The loud and distinctive call is a rising, two-part “truwa-treeeaa.”

Emu

Emu

Dromaius novaehollandiae

Endemic to Australia, this enormous flightless bird has drooping gray shaggy plumage. Only confusion possible with introduced Common Ostrich, but note Emu’s dark head and a shaggy-feathered neck. Hatchlings have distinctive stripes throughout. Juvenile and immature birds are darker than adults with more feathered necks. Prefers open country, where it roams around in loose flocks ranging from a few birds up to hundreds.

Short-tailed Pygmy-Tyrant

Short-tailed Pygmy-Tyrant

Myiornis ecaudatus

Tiny stump-tailed flycatcher; one of the smallest birds on earth. Minute size and compact body give it a unique appearance, in some ways looking more like a bumblebee than a bird. Whitish underparts with green back, gray head, and white spectacles. Found in mature and secondary rainforest, especially in areas with tall trees. Usually perches in the rainforest midstory and can be tricky to spot. Its song is a soft pair of short trilled notes “trrr-trrr,” sounding rather insectlike.
