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.

分布与栖息地

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.

Fasciated Antshrike

Cymbilaimus lineatus

Antshrikes have proportionally large, flat heads and large, hooked bills, and they often cock their tails down. Fasciated Antshrike is widespread through Central and South America. Male is finely barred black-and-white all over with a more solid black cap. Female similar but with buffier ground color and rufous cap. Most often seen in pairs, and often moves higher than other antshrike species, at middle levels or even the canopy of thick edges and tangles. Can be difficult to get a clear view. Listen for series of mournful rising whistled notes.

Sombre Tit

Sombre Tit

Poecile lugubris

Monochromatic tit dressed in black, white, and gray-brown; lacks any bright color. Size and structure similar to Great Tit. Note the contrasting head pattern with narrow white ear patches and an extensive black bib. Inhabits open deciduous forest, Mediterranean scrub, and on rocky mountain slopes. Calls are higher-pitched and faster than Great Tit, but similar to the Blue Tit’s “Si-si-si…” Song is less melodic than Great Tit.

Fire-tailed Sunbird

Fire-tailed Sunbird

Aethopyga ignicauda

Breeding male’s long bright red tail is unmistakable. Female is yellow-green with a grayish head and a rufous tinge to the tail. Immature and non-breeding males are similar to the female, but with a varying amount of bright red on the rump and tail. Breeds in high-altitude forests and scrub up to the treeline, favoring oak and coniferous forest with a rhododendron understory; winters down to around 600 meters, often in forest edge. Gives high thin buzzy calls and twitters.
