Golden-naped Tanager

Chalcothraupis ruficervix

Small, stunning tanager mostly turquoise blue with a buffy vent. Look for black face and small buffy-orange patch on rear crown. Sexes alike. Usually found in pairs, often following a mixed-species flock in the canopy. An Andean species, found in subtropical forests, edges, and gardens. Visits fruit feeders.

识别特征

Golden-naped tanagers have plumage similar to those of the metallic-green tanager, the swallow tanager and the blue-and-black tanager as adults of all three species are primarily blue with black facial masking, however, the golden-naped tanager is the only primarily blue tanager with a golden or reddish crown patch or nape. Females have a similar pattern to males, but have duller colors and a narrower nape patch. Juveniles of both genders have a primarily dull blue-gray coloration with a lighter breast and belly, and lack the distinctive golden nape.

分类信息

The golden-naped tanager was illustrated by the French naturalists Florent Prévost and Marc Athanase Parfait Oeillet Des Murs in 1842. They coined the binomial name Tanagra ruficervix. The type locality is Bogotá in Colombia. The specific epithet combines the Latin rufus meaning "red" and cervix meaning "nape". A molecular phylogenetic study published in 2014 found that Tangara was polyphyletic and in the rearrangement to create monophyletic genera, the golden-naped tanager was moved to the resurrected genus Chalcothraupis. The genus had originally been introduced by the French naturalist Charles Lucien Bonaparte in 1851 with the golden-naped tanager as the type species. The genus name combines the Ancient Greek khalkos meaning "bronze" and thraupis, an unidentified small bird.<p>Six subspecies are recognised:

Solitary Eagle

Solitary Eagle

Buteogallus solitarius

Rare. Very large, short-tailed eagle of highland and foothill forest. Like many hawks, soars mainly in late morning and is very rarely seen perched. Many reports of Solitary Eagle refer to misidentified Common Black Hawk, which also has blackish plumage and a single white tail band on its short tail. The eagle is much larger, with thicker legs, and feet that almost reach the tail tip in flight. Adult Solitary is slaty gray (vs. blackish on Black Hawks). Immature has diffusely patterned brownish tail and dark thighs, unlike black hawks.

Shelley's Francolin

Shelley's Francolin

Scleroptila shelleyi

Medium-sized, beautifully-patterned francolin. Shows rufous patches in the wings in flight. Found on the ground in areas with thick grass, ranging from pure grassland to lush woodland. Mostly at low and moderate elevations, but sometimes found in high mountain grassland. Call is a rhythmic up-and-down repeated “chil-it, chil-chow”. Generally scarce, shy, and retiring. Range does not overlap extensively with similar francolins. Combination of complex facial pattern and belly heavily barred black-and-white are always diagnostic. Much more cleanly and boldly marked than the more washed-out and buffy Whyte’s Francolin.

Sepik-Ramu Shrikethrush

Sepik-Ramu Shrikethrush

Colluricincla tappenbecki

A chunky bird with a thick dark bill. Quite plain: gray-brown on the upperparts and buffy below, with indistinct breast streaking. The breast pattern varies geographically: gray in some areas, contrasting with the buffy belly, and buff in some areas, the same color as the belly. Found at low and middle elevations in humid forest, including secondary forest. Rich, melodious, variable song consists of several penetrating whistles, generally in an up-and-down pattern. Somewhat similar to Rusty Pitohui, but smaller, with a dark rather than pale eye. Similar in size and shape to Sooty Shrikethrush, but never as uniformly blackish. Also similar to Gray Shrikethrush, but smaller, shorter-tailed, and browner, usually with more distinct breast streaking.
