Tatama Tapaculo

Scytalopus alvarezlopezi

This typical “Scytalopus” tapaculo is found only in Colombia’s western Andes. Plumage is gray with a brown tinge to the rump and faint, rusty barring on the lower underparts. Similar to Nariño Tapaculo, Spillmann’s Tapaculo, and Choco Tapaculo, and is best identified by its distinctive voice. Song is a long, pulsating series of frog-like calls that gradually increases in volume and pitch. Inhabits understory of cloud forest and is normally quite hard to see.

Identification

The Tatama tapaculo is almost entirely black, though the underparts are grayish black and the rump has a tinge of dark brown. The flanks and lower abdomen have indistinct bars. Its overall length is about 12 cm (4.7 in) and two males weighed 24.0 and 25.4 g (0.85 and 0.90 oz).

Taxonomy

Though the Tatama tapaculo was first discovered in 1992, it was not formally described until 2017. The South American Classification Committee of the American Ornithological Society accepted it as a new species in May 2019. The International Ornithological Committee followed suit in June 2019 and the Clements taxonomy in July 2019. Its closest relative is the El Oro tapaculo (Scytalopus robbinsi); those two species, Stiles's tapaculo (S. stilesi), and Magdalena tapaculo (S. rodriguezi) form a distinctive clade.<p>The specific epithet honors Colombian ornithologist Humberto Álvarez-López. The English name is taken from Cerro Tatamá, the highest peak in the mountains where the Tatama tapaculo lives.

Range and habitat

The Tatama tapaculo is found primarily on the west side of the West Andes of Colombia, though it "spills over" to the east side of some ridges. It inhabits dense undergrowth in primary cloud forest but apparently shuns secondary forest. On the west side it is found from about 1,300 to 1,750 m (4,270 to 5,740 ft) elevation but on the east side can be found as high as 2,200 m (7,200 ft).

Golden Pheasant

Golden Pheasant

Chrysolophus pictus

Shy and surprisingly difficult to find in mixed and conifer woodland, where it runs quickly from detected disturbance. Red-and-gold male stunning and unmistakable. Female differs from Common Pheasant in strongly barred plumage, dull pinkish (not gray) legs and feet and from Lady Amherst’s Pheasant in lighter barring, more orangeish coloration, and the lack of a bare patch of gray skin behind the eye. Native to China but introduced very locally in Britain and Hawaii; however, captive birds might escape anywhere.

Vinous-breasted Sparrowhawk

Vinous-breasted Sparrowhawk

Tachyspiza rhodogaster

A small hawk with yellow eyes, a lime-green bill base, and yellow legs. Adults are slate-gray above with a vinous breast and dirty white belly and thighs. Immatures are rufous above with diagnostic bold blackish spots and bars and heavily streaked pale underparts. Does not soar. Found primarily in forest from coast to mountains, but also in mangroves and woodlands. Confined to Sulawesi and nearby islands, including the Banggai and Sula Islands. Adult mostly inseparable from Small Sparrowhawk except by call, but largest female Vinous-breasted are longer-bodied, larger-billed, longer-tailed, and longer-toed than largest Small Sparrowhawk. Pale eyes separate Vinous-breasted from Spot-tailed Goshawk and from adult Chinese and Japanese Sparrowhawks. Absence of white tail spots further distinguishes it from Spot-tailed Goshawk, and unbarred thighs separate it from adult Japanese Sparrowhawk. Heavily marked underwings further differentiate it from Chinese Sparrowhawk. Call is a “kew-kew-ke-ke-ke-ke, lower-pitched than Small Sparrowhawk.

Gray Butcherbird

Gray Butcherbird

Cracticus torquatus

Medium-sized ambush-hunter with a long gray bill with a dark, hooked tip. Black head and face with a white nape and throat. Upperparts dark gray, with white rump, mostly black wings (limited white), and black tail with narrow white tip. Rollicking, chuckling song.
