分类信息
The afep pigeon was described by the American ornithologist John Cassin in 1860 from a specimen collected in West Africa from the Ogooué River, Gabon. He coined the binomial name Columba unicincta. The specific epithet combines the Latin uni- "one-" and cinctus "banded". The English name "afep" is the word for a pigeon in the Bulu language of Cameroon. The species is monotypic.

行为
Afep pigeons mainly feed on grain and seeds.<p>They mainly breed in the second half of the dry season. The female pigeon usually lays between 1 and 3 eggs. Both parents help raise the chicks. They are incubated for between 14 and 18 days. They are fed with crop milk after hatching. A few days later, they will start eating small pieces of solid food. They leave the nest 20 to 25 days after they hatch.
保护状况
They are classified by the IUCN as of least concern. Their population is stable and unfragmented, though the exact number of birds is unknown.

Oriental Hobby
Falco severus
Small falcon, usually seen in and around forest clearings or perched up on high vantage points such as snags and telecommunication towers from which it hawks for its prey. Dark gray above with brick-red underparts and a white throat and collar. One of very few small falcons throughout much of its range; can be confused with migratory Eurasian Hobby, which lacks the reddish underparts.
Pine Warbler
Setophaga pinus
A medium-sized, rather robust and long-tailed warbler, with a noticeably stout bill. Variable plumage, from bright adult males with extensive yellow throat to extremely dull grayish-brown immature females. Always look for two white wingbars, diffuse streaking on the sides of the breast, large bill, and long narrow tail with a shallow notch. Well-named: almost always found in pine trees throughout the year. In spring and summer, listen for loud musical trill (compare with Chipping Sparrow and Dark-eyed Junco). Occasionally visits feeders, especially for suet. A short-distance migrant, wintering entirely in the United States.
White-winged Lark
Alauda leucoptera
Handsome lark with flashing white wing patches. Note streaky gray-brown back, white underparts, and warm rufous shoulder; male also has distinct red cap and ear coverts. Forages in large flocks outside of the breeding season. Favors wide expansive dry steppelands and fields; occasionally encountered in agricultural areas. Song is a jumble of trills, chirps, harsh rasps, and twittering notes.
