Pemba Green-Pigeon

Treron pembaensis

A medium-sized, chunky pigeon that has an olive-green back and a gray head and underparts. Flight is fast and direct. Sometimes seen alone, though more often in small groups. Found in forest, forest edge, plantations, and villages, often around fruiting trees. Similar to other green-pigeons, but easily separated by range, as it is the only green-pigeon on the island of Pemba. Voice is a quiet but maniacal series of sputters, whistles, and cackles. 

识别特征

The Pemba green pigeon (Treron pembaensis) is a species of bird in the family Columbidae. It is a small and stocky pigeon, with an average length of 25 cm. The head, neck, breast, and underparts are greenish-grey, while the upperparts from the lower mantle to the rump are olive-green, brighter on the rump and uppertail-coverts and with a greyish wash elsewhere. There is a dark greyish-purple patch on the shoulder formed by the lesser wing-coverts. It is endemic to Pemba Island, off the northeastern coast of mainland Tanzania. It is most common in primary forest, but also occurs in secondary forest, gardens, and clove plantations. Its population is estimated to number 2,000–3,200 mature individuals, although some estimates are as low as 500.

Owston's Tit

Owston's Tit

Sittiparus owstoni

Small songbird found only in evergreen broadleaf forests on southern Izu Islands of Japan. Stunning in plumage, with deep rusty body, dark gray wings and tail, and black throat and crown patch. Formerly considered a large subspecies of Varied Tit, but note the much darker rusty face. Call similar to Varied but higher-pitched, with more frequent, forceful whistles between the nasal notes.

Mount Kupe Bushshrike

Mount Kupe Bushshrike

Chlorophoneus kupeensis

A grayish bushshrike with green wings and tail and a unique head pattern: the black mask curls down to form a narrow black breast band surrounding the white throat. Some morphs have a purple dot at the base of the throat. Juvenile has less distinct face pattern than adult. A rare resident, restricted to a handful of sites in the Cameroon-Nigeria highlands, where it is found singly and in pairs in the canopy of primary hill forest between 930 and 1550 meters of elevation. Calls include an electric grating “cha-cha-cha-chggrrt-chggrrt-chggrrt” like a laser-gun sound effect in a computer game, as well as harsh croaking, whistles, and ticks. May snap wings when agitated. 

Australian Fairy Tern

Australian Fairy Tern

Sternula nereis

Very small coastal tern with forked tail. Nests on sandy beaches, where it is sensitive to disturbance. Very similar to Little Tern, which overlaps in range in parts of southern Australia. In breeding plumage, note yellow bill (in southern Australia lacking black tip) and orange-yellow legs. In contrast to Little Tern, Fairy has a gap between the black in front of eyes and the bill (in breeding Little, the black extends to the bill). In nonbreeding plumage, bill much darker. Hunts by flying low over the water and plunging down to snatch prey from the surface. New Zealand subspecies very rare and breeds only at four sites on the east coast of the southern Northland.
