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.

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.

Pitt Island Shag
Phalacrocorax featherstoni
A small, slender gray shag, with a slender bill, yellow legs and feet, and small dark spots on its shoulder and wing feathers. Feeds, roosts, and breeds around rocky shorelines of the Chatham Islands. The Chatham Islands Shag and the Great Cormorant are the only two similar species with overlapping range, distinguished by the white upper wing patch on the Chatham Islands Shag and the much darker overall appearance and larger size of the Great Cormorant. The Pitt Island Shag is the only shag found on the Chatham islands to have yellow legs and feet.
Green Malkoha
Ceuthmochares australis
Odd, dark, green-and-gray cuckoo with a bright yellow bill. Found in thick habitats including forest, forest edge, and thickets. Skulks in the thickest parts of the mid-story, especially preferring vine tangles. Call starts with a hesitant series of high “kik” notes, eventually followed by a long, accelerating trill. Dark coloration and yellow bill are distinctive. Range does not overlap with the similar Blue Malkoha.
Long-legged Buzzard
Buteo rufinus
A large, long-winged buzzard which may recall a small eagle in size. Variable plumage with three color morphs. All have obvious dark carpal patches at the wrist of the wing. Juveniles lack the adult’s prominent black trailing edge to the wings. Often hunts from a prominent perch, or sits on the ground and scans for prey. A species of open steppe and desert country, sometimes in more wooded areas but always near big open spaces. Compare with similar Common and Upland Buzzards, as well as Rough-legged Hawk; note long-winged structure, size, and wings held in “V” in soaring flight.
