Moheli Scops-Owl

Otus moheliensis

Small, compact dark owl with small ear tufts. The overall coloration is variable, and can be rufous or dark brown. Found in remnant lowland rainforest, secondary forest, and plantations on the island of Moheli, in the Comoros. The remarkable vocalizations include a raspy bark and a long, low-pitched growling hiss. Sometimes active and vocal during the day, especially the early morning and late afternoon. Easily identified, as the only other owl on Moheli is the much larger Barn Owl.

分布与栖息地

This owl is found only on the mountain in the centre of the island of Mohéli, the total range covering 21 km2 (8.1 sq mi), including the highest point of the ridge, at 790 m (2,590 ft) in altitude, and the adjacent upper slopes. It occurs in dense humid forest, which is rich in epiphytes between 450 and 790 m (1,480 and 2,590 ft).

行为

The Moheli scops owl is strictly nocturnal and becomes active only after sunset. Calling males have been recorded in September. The diet is probably mainly made up of insects.

保护状况

The species was only described in 1998. It has an estimated population of 400, and is classified as critically endangered due to it being restricted to such a small area, which is being rapidly deforested. In 1995, only five percent of the island still had intact, dense, humid forest. As well as habitat loss, other threats to the Moheli scops owl include hunting and black rats, which may eat its eggs and young but also compete with it for food. At present, the montane forest where the Moheli scops owl occurs is not protected.

Antipodean Albatross

Antipodean Albatross

Diomedea antipodensis

Huge albatross of the Southern Ocean. Two subspecies: “Gibson’s” breeds primarily on Auckland Island and ranges at sea around New Zealand and eastern Australia; “Antipodean” breeds mostly on Antipodes and Campbell Islands and ranges mainly across Pacific to Humboldt Current off Chile. Plumage highly variable, starting chocolate-brown with a white face and gradually becoming whiter over many years. Younger birds separated from Southern Royal Albatross by darker tail, brown markings on head and back, and lack of black “lips” on cutting edge of bill. Older birds more difficult to separate; focus on more coarsely marked upperwings, often with conspicuous white patch in center of wing, and lack of black “lips”. Often shows orange stain on cheek, never shown by Southern Royal. Identification from other Wandering-type Albatross is extremely difficult and often presumed by range. Older “Antipodean” often retain complete dark cap, tail, and upperwings.

Chestnut-vented Nuthatch

Chestnut-vented Nuthatch

Sitta nagaensis

Typical nuthatch; small bird with a wedge-shaped head, usually seen clambering around on trees. Gray above and white below, with a thin black line extending from the bill base to the shoulder. Deep rust red on the flanks and red-edged scaling under the tail serve to distinguish this otherwise plain species from similar nuthatches. Active and social, often following mixed flocks. Inhabits both broadleaf and coniferous forests in foothill and submontane areas. Listen for its song, a loud ringing series of trills. Calls include nasal caws, a bright-sounding “pewpewpew,” and high-pitched chittering.

Jameson's Antpecker

Jameson's Antpecker

Parmoptila jamesoni

A small, slender-billed, warbler-like waxbill with pinkish-brown legs and different-looking sexes: the male has a red forehead, dull brown upperparts, and a rusty-chestnut face and underparts, while the female has a tawny-brown face and cheeks, pale buff underparts with scattered dark chevrons, and dull brown upperparts. Pairs and small groups forage by themselves or in mixed-species flocks, in the understory and middle levels of primary, secondary, and gallery forest, often near water. Eats insects, with a fondness for ants. Call is a high-pitched, downslurred “whseet.”
