Cameroon Mountain Greenbul
Arizelocichla montana
A medium-sized greenbul of the mountains of Cameroon and southeastern Nigeria. Remarkably uniform yellow-olive in plumage, with a red eye. Found in montane forest, secondary habitat, and scrub. Feeds in the understory and at middle levels of the forest. Somewhat similar to Western Mountain Greenbul, but easily separated by the lack of a gray head and contrasting white eye crescents. Might be confused with Cameroon Olive-Greenbul, but separated by brighter coloration overall and an olive-green rather than reddish-brown tail. The song is a chirpy series of nasal notes that ends with an accelerating flourish.
识别特征
The Cameroon mountain greenbul (Arizelocichla montana) is a species of the bulbul family of passerine birds. It is found in the Cameroonian Highlands forests. It is suspected to become rarer due to habitat loss, largely from agriculture, although this is not enough to approach the thresholds for Vulnerable status.
分类信息
The Cameroon greenbul was originally described in the genus Andropadus and, was re-classified to the new genus Arizelocichla in 2010. Alternatively, some authorities classify the Cameroon greenbul in the genus Pycnonotus. Alternate names for the Cameroon greenbul include Cameroon little greenbul, Cameroon montane greenbul, Cameroon mountain greenbul, montane greenbul and mountain little greenbul. The alternate names mountain bulbul and mountain greenbul should not be confused with the species of the same name (Ixos mcclellandii and Arizelocichla nigriceps respectively). The name 'Cameroon greenbul' is sometimes used as an alternate name for the Slender-billed greenbul.

Red-and-white Crake
Rufirallus leucopyrrhus
Uncommon and very difficult to see; usually detected by voice, a throaty chatter. Favors wetlands with tall coarse grasses. Note rufous head, brownish back, and white throat and breast with black-and-white broken stripes on the flanks and vent. Lacks the dark cap of the similar Rufous-sided Crake.
Choco Tyrannulet
Zimmerius albigularis
Small flycatcher found in canopy of lowland and foothill forest in northwestern Ecuador and southwestern Colombia. It has olive-green upperparts, pale gray underparts, yellow spectacles, and yellow fringes to the wing feathers. May overlap with the very similar Golden-faced Tyrannulet in the western Andes of Colombia; in that region, ID is best confirmed by voice. Vocalizations include a soft whistle repeated every few seconds and a quick series of rising notes. Perches conspicuously high in the trees, and often holds its tail partly cocked.
Antioquia Bristle-Tyrant
Pogonotriccus lanyoni
Rare flycatcher known only from a few sites in the Colombian Andes, mainly in the northern part of the central range. It is fairly small and mostly yellow, with a gray crown and broad, yellow wingbars. Yellow and gray smudges on ears can be very indistinct. Often confused with the much more common Yellow-olive Flycatcher, but bill is narrower, wingbars are brighter yellow, and voice is different. Typical song is a short burst that starts off as a dry rattle and then morphs into airy squeaking. Inhabits humid forest and sometimes joins mixed species flocks.
