Madagascar Ibis
Lophotibis cristata
A rather fantastical forest-dwelling ibis with a colorful face, white wing, and rich brown body. Endemic to Madagascar, where it is most frequently encountered in eastern rainforest, though it also occurs locally in western deciduous forest. Roosts and nests in trees, and feeds on the forest floor. Extremely shy, and unless spooked will rapidly flee from disturbance on foot. Very loud and vocal, giving a long and agitated series of wheezy, whining notes. Calls most often at dawn and dusk and during the night.
Identification
The Madagascar ibis, with a length of 50 cm (20 in), is among the largest birds in the Madagascar forest. The head is black and the upper parts are rufous brown. The chin, neck and throat and underparts are dark brown and the wing largely white. Part of the face is naked and red, including round the eye, and the crown and back of the neck bear a crest of long feathers which are black with a metallic sheen. In the subspecies L. c. cristata, the sheen is green and there are flecks of white; in the subspecies L. c. urschi, the throat, neck and crest have a greenish sheen mixed with yellowish-orange, and the body colour is darker chestnut. The iris is brown, the very long beak is horn-coloured and the legs and feet are red.
Taxonomy
The Madagascar ibis was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in 1781 in his Histoire Naturelle des Oiseaux from a specimen collected on the island of Madagascar. The bird was also illustrated in a hand-coloured plate engraved by François-Nicolas Martinet in the Planches Enluminées D'Histoire Naturelle which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text. Neither the plate caption nor Buffon's description included a scientific name but in 1783 the Dutch naturalist Pieter Boddaert coined the binomial name Tantalus cristatus in his catalogue of the Planches Enluminées. The Madagascar ibis is now the only species placed in the genus Lophotibis that was erected by the German naturalist Ludwig Reichenbach in 1853. The name of the genus combines the Ancient Greek lophos meaning "crest" and ibis; the specific epithet cristata is from the Latin crustatus meaning "crest".

Peruvian Racket-tail
Ocreatus peruanus
Fantastic cloud forest hummingbird found in the eastern Andes from southern Colombia to central Peru. Male has a straight tail ending in rackets and buffy leg puffs. On female, note the combination of short bill, white underparts scaled with green, white facial marks, and buffy thighs. She is quite similar to female Rufous-vented Whitetip, but has buff (not white) thighs and fewer markings on throat. May overlap with Rufous-booted Racket-tail at the southern edge of its range; male Peruvian Racket-tail has straight central tail feathers that do not cross; females of the two species look almost identical. Typically feeds at small flowers at forest edge or in clearings, and sometimes visits feeders.
Steppe Eagle
Aquila nipalensis
A large eagle with rich brown plumage, wide wings, and seven well-splayed “fingers” at the wingtip. Adults are entirely dark brown; juveniles and immatures at rest show a distinctive wide white band bordered with black on the wing. In flight, this transforms into a white traverse band on the underwing that forms the base of the primary and secondary feathers. Birds take about four years to attain adult plumage. Frequents open grasslands, deserts, scrub, wetlands, and mountains, and is a regular carcass feeder along with vultures.
Eastern Screech-Owl
Megascops asio
Small, stocky owl with large head and no neck. Pointed ear tufts are often raised. Varies in color from gray to bright rufous (reddish-brown). Intricate pattern is perfect for camouflage against tree bark. Yellow eyes. Active at night when they prey on small birds and mammals. More often heard than seen; listen for its descending whinny and longer trill. Roosts and nests in cavities, including nest boxes. Found in a variety of habitats with trees, particularly near water.
