Slender-billed Greenbul

Stelgidillas gracilirostris

Slim, long-tailed greenbul with an olive-brown back and gray underparts. When seen well, shows a red eye. Found in the canopy of humid forest. Can be found singly, in pairs, or in small groups. The most common vocalization is a long, descending whistle: “teeeiow.” The contrast between the dark upperparts and gray underparts make this a distinctive species by greenbul standards.

分类信息

The slender-billed greenbul was formally described in 1844 by the English naturalist Hugh Edwin Strickland under the binomial name Andropadus gracilirostris from a specimen collected on the island of Fernando Pó (now Bioko) off the west coast of Africa.<p>A molecular phylogenetic study of the bulbuls published in 2007 found that Andropadus was non-monophyletic. In the subsequent rearrangement to create monophyletic genera, the slender-billed greenbul was moved to the genus Stelgidillas that had been introduced by Harry C. Oberholser in 1899. Alternate names for the slender-billed greenbul include the Cameroon sombre greenbul and Cameroon greenbul. The latter name should not be confused with the species of the same name, Arizelocichla montana.<p>Formerly, some authorities also considered the following species (or subspecies) as species within the genus Stelgidillas:<p>Two subspecies of the slender-billed greenbul are recognized:

Streptopelia xanthocycla

Large, pale dove of dry, open country and cultivation in the lowlands. Pale gray head, darker on the back, pinkish-gray chest, black crescent on the nape, fairly long tail with white corners and a distinctive pale yellow eye-ring.

Red-headed Malimbe

Red-headed Malimbe

Malimbus rubricollis

A striking black-and-red forest malimbe lacking a breastband in either sex. Male has red from the forehead to the upper back, with spurs creating a half-collar on the neck. Female is like the male but the forehead is black to the center of the crown. Juvenile is like the female, with a paler bill and a brown forehead. A common resident in its range, preferring the canopy of primary and secondary lowland forest, farmbush, woodland, and occasionally gardens. Forages nuthatch-style in pairs and small groups and often dangles upside down, clinging to branches and examining crevices. Vocalizations include whistles accelerating into sizzling notes “whetdoteew-dzrsrsrrrr.”

Lesser Ground-Robin

Lesser Ground-Robin

Amalocichla incerta

A fairly small, long-legged bird of montane forest floor. Brown above with rufous edges to the flight feathers, buffy chest, white throat, and white spot behind the bill. Same general shape and habits as the Greater Ground-Robin, but Lesser occurs at lower elevations and is much smaller. Heard more often than seen. Song, a series of whistled notes, either rising, falling or the same pitch.
