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.

行为
Like most owls, the Madagascar owl is nocturnal, roosting by day in dense foliage. It feeds mainly on small mammals, hunting either in the forest or in open areas nearby. Pellets collected from a roost site in southeastern Madagascar were examined and contained the remains of insects, frogs (Boophis), geckoes (Uroplatus), birds (broad-billed roller and Malagasy bulbul), rodents, including tufted-tailed rats (Eliurus spp.) and black rat (Rattus rattus), Commerson's leaf-nosed bats (Hipposideros commersoni), and mouse lemurs (Microcebus spp.).<p>Little is known about its breeding biology. It is thought to lay its eggs in stick nests created by other animals, like the closely related long-eared owl.

Green-capped Tanager
Stilpnia meyerdeschauenseei
Handsome tanager with a small range in the Andes of western Bolivia and southeastern Peru. It is pale with blue wings and tail, black mask, and buffy crown and vent. Similar to Burnished-buff Tanager, but has a duller, less rusty crown and is found at higher elevations. Inhabits lightly wooded areas and edge, avoiding areas of dense forest.
Stubble Quail
Coturnix pectoralis
Large, strongly marked quail with pale breast/belly with heavy dark streaks. Note bold pale eyebrow. Male has orange throat contrasting with blackish breast. Typically found in drier grasslands. As a flushed bird descends to land, it often slows down in flight before dropping into cover; look carefully for a pale patch on the leading-edge of the wing as it drops.
Clark's Nutcracker
Nucifraga columbiana
This relative of jays and crows is pale gray with a whitish face and black wings. Sexes are similar; juveniles are browner than adults. Found almost exclusively in coniferous forests at high elevations; feeds on pine cone seeds and stashes thousands of them in various places to eat later in the winter. Often found in flocks. Sometimes visits feeders. Similar in color to Canada Jay, but especially note bill shape: long, slender, and sharply pointed.
