Great Eared-Nightjar
Lyncornis macrotis
Unique, feline-looking nightjar. Distinct ears and frequently erect posture distinguish it from many other nightjars. Plumage consists of complex shades of browns which can vanish into the background when perched. Noticeably long-tailed in flight. Inhabits forests, forest edges, and fields and plains with some tree cover. Gives a loud “bee-AHWEE!”
识别特征
The great eared nightjar is the largest species in the family in terms of length, which can range from 31 to 41 cm (12 to 16 in). Males weigh an average of 131 g (4.6 oz) and females weigh an average of 151 g (5.3 oz), making it the second heaviest species in the family after the nacunda nighthawk.
分类信息
The great eared nightjar was formally described in 1831 by the Irish zoologist Nicholas Aylward Vigors based on a sample collected in the neighbourhood of Manila in the Philippines. Vigors coined the binomial name Caprimulgus macrotis. The great eared nightjar was formerly placed in the genus Eurostopodus. It and the closely related Malaysian eared nightjar were moved to the resurrected genus Lyncornis based on the results of a molecular phylogenetic study published in 2010 that found large genetic differences between the great eared nightjar and other species in Eurostopodus. The genus name Lyncornis combines the Ancient Greek lunx / lunkos (meaning "lynx") with ornis, meaning "bird". The specific epithet macrotis is from the Ancient Greek makrōtēs, meaning "long-eared" (from makros meaning "long" and ous, ōtos meaning "ear").<p>Five subspecies are recognised:

行为
Like other nightjars they are active at dusk and at night. They have a distinctive call which includes a sharp tsiik followed by a pause and a two-syllable ba-haaww.<p>The nest is a scrape on the ground and the clutch consists of a single egg. The chick is well camouflaged among leaf litter.

Bornean Peacock-Pheasant
Polyplectron schleiermacheri
With his iridescent pale blue crest, bright orange facial skin patch, and luminous blue spots along his wings and broad fan-shaped tail, the eccentric-looking male is unmistakable if seen well. Female is less eye-catching: warm brown all over with smaller, darker spots. Inhabits primary lowland and hill forest, favoring areas with ridges. Typically quiet; occasionally gives loud, harsh calls.
White-headed Vanga
Artamella viridis
Mid-sized black-backed vanga with a typical bill. Males are pure white on the head and underparts, while females are pale gray. Madagascar endemic that is found at low and middle elevations in all forest types, and sometimes in adjacent plantations and scrub. Vocalizations include harsh scolds and penetrating hollow whistles. Larger than Chabert Vanga, with a completely pale head. Smaller than Sickle-billed Vanga, with a much shorter bill.
Sclater's Antwren
Myrmotherula sclateri
Small yellow-and-black streaked antwren of mature rainforest canopy. Males are yellow with extensive black streaking; females are similar, with a reddish wash in the face. Yellow throat of both sexes distinguishes them from similar Pygmy and Moustached Antwrens (with white or buffy throats); female Sclater’s also have streaking on the center of the breast, unlike those species. Moves singly or in pairs with mixed species flocks in the forest canopy, but very difficult to see, and much more often heard. Listen for a slow series of 3-6 whistles, “wheew, wheew, wheew, wheew,” similar to a Fasciated Antshrike song but higher pitched and slightly weaker.
