Madagascar Owl
Asio madagascariensis
Fairly large, brown owl with long ear tufts. Endemic to Madagascar, where it is found locally in all forest types, and sometimes in scrub and plantations. Usually roosts high in a tree, often in an introduced pine tree. Call is a series of nasal barks, similar to White-browed Owl but less quick and emphatic. Similar in size to Marsh Owl, but has prominent ear tufts and a pale chest with fine streaks. Much larger than Malagasy and Torotoroka Scops-Owls.
识别特征
The Madagascar owl is similar in appearance to the Holarctic long-eared owl in that it sits tall and at rest shows prominent ear tufts. The plumage is mainly brown with darker streaks and bars. It has distinctive bright orange eyes. The adults are brown above, and mottled with buff, especially across the mantle. The face is plain dark buff, with darker brown feathers around the eyes, on the edge of the facial disc, and on the ear tufts. The underparts are light brown with darker brown streaks which fade away towards the vent. The juvenile is covered in white down contrasting with a black facial disk and dark brown wings. It ranges from 40–50 cm (16–20 in) in length, making it the largest of the country's owls; females are larger than males.<p>Its call is usually a series of barks, varying in pitch and volume, but sometimes it will utter a series of more hoot-like notes, described by some as ulooh.

分布与栖息地
The Madagascar owl is endemic to Madagascar, where it is widespread in the west and centre of the island. It is generally found at elevations ranging from sea level to 1,600 m (5,200 ft), though it occasionally ranges as high as 1,800 m (5,900 ft). It inhabits a variety of woodland habitats, mainly in the drier western forests, although it appears quite adaptable, and also occurs in degraded habitats, even on the central plateau where the forest cover has been fragmented.

McKay's Bunting
Plectrophenax hyperboreus
Rare white snowball shrouded in mystery. Nonbreeding birds have buffy fringes to head and back feathers that wear to white by spring. Breeding males almost pure white except for limited black in wings. Breeding females have dark streaking on back. Breeds almost exclusively on St. Matthew Island in the Bering Sea; winters on the coast of western Alaska. Very similar to Snow Bunting but paler, usually with white rump; intermediate birds may be hybrids.
White-winged Nightjar
Eleothreptus candicans
Small, distinctive nightjar, pale gray overall with dark brown spots. Note the white eyebrow and moustachial stripe. In flight, males exhibit white underwings and undertail and black flight feathers. Found at a precious few open savanna grassland sites with scattered trees, especially those with numerous termite mounds known as earthmound fields.
Peacock Coquette
Lophornis pavoninus
Tiny hummingbird of tepui highlands. Both sexes distinctive: males have long cheek tufts with black spotting, while females are heavily streaked below. Both have a white rump band like other coquettes. Found only in humid forest and scrub in the tepui region. Feeds on nectar by infiltrating territories of larger hummingbirds; also presumably eats tiny insects. May be seen resting on exposed perches. Both sexes are darker than other coquettes in range, and this species typically occurs at higher elevations than others.
