From the family of Anatidae

The Duck is so named after its striking calls. The Whistling Duck aka known the Tree Duck is both aquatic as well as land based. But it seldom perches, in the daylight hours remain in the water or standing on land. It moves and lives in flock. Sometimes could be small as 5-6 birds but when possible, gathers in fairly large flock of hundred bird

Whistling Duck are nocturnal feeders and in the day, they gather in flocks in wetland and lakes that has good vegetation cover. Undisturbed they do feed otheriwse just floating and gazing. They can perch on tree but hardly do so but they build their nest in the hollow of the trees. Also seen were nest built at the fork of trees. That's where they acquire the other name of Tree Duck.

These Ducks are gregarious at times and feed mainly on plants they gather from the water surfaces. They do dabble and dive but not so often seen and feed on small fish, frogs and other invertebrates such as mollusks and worms.

In flight, the Whistling Duck held their head below that level of the body, flying slowly with rapid wing flapping. Without fear or any intention of leaving their place of roost, they would circle giving out that continuous calls. This brown colored Duck has long neck with broad wings producing that distinctive 2-notes wheezy call from the sky.

 My personal jottings on the Lesser Whistling-Duck:-

More so in ponds with little pollution and with lots of vegetations. They were also in waterways and river with vegetation on the banks.

 

The numbers in Bidor was impressive in right season with the field filled and when they took off, it was like  dark cloud in the sky. The flock do not tolerate the approaches made by humans and would take flight at the slightest initiative.

In Pulau Burung, quite a different scene. The Ducks gathers in groups of 4-8 birds and were scattered around the whole pond. These batches of Ducks would stay put and showed no apprehension with birders walking up and down the edge of the pond. Distance could be as close as 50 meters. The last few photos on this page are scenes from Pulau Burung.
