Meller's Duck
Anas melleri
Large brown duck that is endemic to eastern Madagascar. Its plain brown plumage, blue-gray bill, and large size distinguish it from all other ducks in Madagascar. In flight, look for green and white stripes in the wing. Found mostly at middle elevations, on lakes, streams, rivers, and freshwater wetlands that are usually within or adjacent to rainforest. Rare and endangered.
Identification
The Meller's duck resembles a large female mallard. At 55–65 centimetres (22–26 in), it averages slightly larger than a mallard and is at the top size for the genus Anas. However, as opposed to most mallard relatives, they lack a supercilium. The speculum feathers are green as in some of its relatives, but unlike in these, it is bordered white as in the mallard. Its body is dark brown with narrow paler fringes to feathers on upper parts and wider fringes on lower parts. Its bill is pale grey, with dark patches at the base, and is larger than normal. Its feet and legs are orange.

Behavior
Meller's duck breeds apparently during most of the year except May–June on Madagascar, dependent on local conditions; the Mauritian population has been recorded to breed in October and November. Unlike most of their closer relatives—with the exception of the African black duck—they are fiercely territorial during the breeding season; furthermore, pairs remain mated until the young are independent.
Conservation
This species is listed as an endangered species by the IUCN Red List. The Lac Alaotra wetlands, where historically the largest number of these birds was to be found, have suffered habitat destruction on a large scale in the latter half of the 20th century, and local waterbird populations have declined dramatically. The Madagascar pochard was rediscovered in 2006, though not in the Lac Alaotra area.<p>The conservation of this species was long hampered by its—entirely erroneous, see below—dismissal as a variant of the mallard which deserved no special interest. Due to its drab plumage and territorial habits, this species is not very popular among aviculturalists, although it reproduces readily in captivity like most ducks if enough space and good habitat are provided. Although a captive breeding program exists (part of the European Endangered Species Programme), the species is not very often kept in zoos either; it can be more frequently seen in Europe, such as in EEP members Cologne Zoo, Edinburgh Zoo, Durrell Wildlife Park, and Zürich Zoo.[citation needed]

Other Birds
Little Bustard
Tetrax tetrax
A small brownish bustard with long legs and neck. May crouch if disturbed but when flushed, explodes noisily into a grouselike flight with whirring wings. Striking white wings with black tips are prominent in flight. Breeding-plumaged males are distinctive with black neck and double V-shaped white collar. Usually fairly quiet and unobtrusive. Found in open plains with shrubs and sufficient ground cover to hide in.
Sumatran Leafbird
Chloropsis media
Uncommon and declining Sumatran endemic, restricted to foothill forest at 600-1000 meters. A typical leafbird, with a predominantly bright green body in both sexes. Male has a dark “half-mask” and throat, as well as a dark purplish-blue malar stripe. Female has a faint sky-blue malar stripe, but otherwise lacks dark coloration on her face. Both sexes have a yellow forecrown and a blue shoulder patch. Juvenile is unmarked green all over, with a faint yellow eyering. Compare with Greater Green Leafbird, Lesser Green Leafbird, and Blue-winged Leafbird, none of which have a yellow forecrown. Loud, musical song incorporates mimicry.
Pacific Heron
Ardea pacifica
Large dark gray heron with white head and neck. In flight shows white "headlights" on the leading edge of the wing. Typically has dark legs. Usually found near water. Often seen singly, but also occurs in large scattered groups while foraging in damp paddocks and grassland.
