Spectacled Tyrant
Hymenops perspicillatus
Fairly common locally in fresh and brackish marshes and wet pastures, where male is often conspicuous, perching atop bushes or wires. Besides his glossy black plumage with yellow bill and eyering, the male often attracts attention by big white wing patches that flash in flight. The very different female is much less noticeable and often keeps to vegetation. Female is overall streaky with a yellowish bill and eyering, and bright rusty wing flashes. Compare with female Yellow-winged Blackbird.

The spectacled tyrant was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the wagtails in the genus Motacilla and coined the binomial name Motacilla perspicillata. Gmelin based his description on "Le clignot ou traquet à lunette" that had been described in 1778 by the French polymath the Comte de Buffon in his Histoire Naturelle des Oiseaux. The spectacled tyrant is now the only species placed in the genus Hymenops that was introduced in 1828 by the French naturalist René Lesson. The genus name is from Ancient Greek humēn meaning "skin" or "membrane" and ōps meaning "eye". The specific epithet perspicillatus is Modern Latin meaning "spectacled". Within the family Tyrannidae the spectacled tyrant is sister to the genus Knipolegus containing the black tyrants.<p>Two subspecies are recognised:

Ruff
Calidris pugnax
A bizarre and unique shorebird. Medium-sized with fairly short, slightly drooped bill. Leg color varies from dull greenish to bright orange; bill can be entirely dark or mostly orange. Plumage highly variable, especially breeding males, which have fancy neck ruffs that can be black, white, buffy, reddish-brown, or any combination thereof. Females and nonbreeding birds can be confusing, usually plain grayish-brown overall, sometimes with blotchy markings on the neck and belly. Juveniles are bright buffy with neat scaly patterning on the upperparts. Flight often rather lazy, with deep floppy wingbeats; note white underwings, white sides to rump, and feet projecting well past tail. Males are much larger than females. Breeds in bogs and wet grassy meadows across northern Eurasia; winters mainly in Africa but also across India and Southeast Asia. Migrants occur in almost any wetland habitat, from reservoirs and fields to coastal mudflats. Feeds by probing and picking, often while in shallow water. Rare but regular vagrant to North America, usually single birds found among flocks of yellowlegs.

Gould's Frogmouth
Batrachostomus stellatus
Cryptic, seldom-seen nightbird of lowland and foothill forests. Unlike other small frogmouths, sexes are alike. Light morph is bright rufous with scattered white dots on the wings and mottled-white underparts. Dark morph is brown but with the same general patterning. Compare with Sunda Frogmouth: male Sunda is much more heavily marked with white above and has patchier markings on the underparts, while female Sunda has a prominent white band across the chest. Sumatran and Bornean Frogmouths inhabit higher elevations. Song is a loud “weeow-wah.” Calls include “weeow” and a rapid series of “wuk” notes that resembles a thrush’s alarm call.

Madagascar Pochard
Aythya innotata
Extremely rare diving duck that was long thought extinct before being rediscovered in 2006 in a remote site in northern Madagascar. A large duck that is mostly rich brown, with white under the tail. Shows a conspicuous white wing stripe in flight. Males have a pale eye and females a dark one. Lives on freshwater lakes and wetlands. Dives frequently, like a grebe, but is much larger. Lacks the pale face of White-faced Whistling-Duck. Smaller than Meller’s Duck, with darker brown coloration and white under the tail.
