Malagasy Harrier
Circus macrosceles
A typical harrier, with long slender wings and tail and graceful swooping flight. Male has pale gray panels in the wings, while female is browner and more uniform. Found mainly in open habitats, including marsh and montane grassland. Occasionally seen flying over forest. Spends long periods on the wing and is rarely seen perched. Most often confused with Black Kite, but has longer wings, a longer, narrower, and un-forked tail, a white rump, and pale underparts. Coloration overall similar to other raptors like Madagascar Buzzard, but lanky harrier shape is distinctive.
Identification
It is about 42–55 cm long; the female is up to 13% larger than the male. The male has a blackish back and a greyer head with dark streaks. The underparts and rump are whitish and the tail is grey with dark bars. The forewings and wingtips are blackish while the secondaries are grey with dark bars. Females are browner than the males.<p>The Réunion harrier is smaller and darker with shorter legs and shorter, more rounded wings. Males have a blacker head and plainer secondaries and tail.

Range and habitat
In Madagascar it is found in marshland and grassland across the island except for the south. It is generally scarce with the largest numbers in the north-west. It occurs from sea-level up to 1800 m. On the Comoros it is more often found in drier habitats and in forested areas. It has occurred on all four main islands but there are no recent records from Mayotte.<p>Its population size is uncertain but is estimated to be between 250 and 999 individuals. It is thought to be declining as a result of hunting and habitat destruction and is classed as endangered by BirdLife International.

Behavior
It feeds mainly on birds such as the Madagascar partridge and also takes reptiles, amphibians, rodents and insects. It typically feeds by flying low over the ground and dropping down rapidly when it spots its prey. It will also hunt over the canopy of forests.<p>It breeds in marshland, building a nest of grass and stems on the ground or low in a bush. The white eggs are incubated for about 32–34 days and the young birds fledge after 42–45 days.

Other Birds
Slaty-backed Hemispingus
Poospiza goeringi
A beautiful small tanager with attractive contrasting colors: slate gray upperparts, orange underparts, black mask, and a bright white eyebrow. Sexes similar, but male is richer orange. Often found in pairs, small groups and mixed species flocks. Uncommon in upper cloud forest, elfin forest, and bamboo edges, most often foraging at lower levels. Voice is an energetic and rapid series of disordered notes. No similar species with its color pattern and prominent eyebrow. Endemic to the Andes of Venezuela.
Masked Apalis
Apalis binotata
A small, slender warbler with greenish upperparts and reddish eyes; gray crown and cheeks are separated from the black throat by a striking white moustache. Juvenile has a green crown and a yellow throat. Locally common at scattered locations in lowland forest below 1500 meters of elevation, preferring the lower strata of primary and secondary forest and scrub in clearings. Pairs give a continuous buzzy “dree-lip, dreep-lip, dree-lip” and a dry “strik-strik-strik.” Masked Apalis looks similar to some montane forest apalises, but Black-throated Apalis has a striking yellow-orange belly, and Black-faced Apalis, an Albertine Rift endemic, has a black crown and the moustachial streak reduced to a neck spot.
African Pied Wagtail
Motacilla aguimp
The only black-and-white wagtail in Africa shows a bold white eyebrow and wing panels and a broad black throat patch. The juvenile is brownish. Pairs and family groups frequent a broad range of habitats, including human-altered environments, but in drier areas they are associated with waterside habitats. The species runs on the ground foraging for insects, characteristically wagging its tail up and down in an exaggerated motion. The juvenile African Pied Wagtail may resemble the Cape Wagtail, but has extensive white panels in the wings.
