The spotted whistling-duck usually occurs in pairs or small groups, often with other duck species (3) (4) (5), although it will frequently roost in larger numbers in the tops of tall trees (3). This species moves to and from its roosting sites at dusk and dawn (3).
Little information is available on the feeding behaviour of the spotted whistling-duck, but it is thought to graze on short grass and to dabble for food in water (4). Like other whistling-ducks, the spotted whistling-duck is quite long-legged and is at home both in the water and walking on dry land (3).
The timing of the spotted whistling-duck’s breeding season appears to vary, but it is thought to usually begin at the start of the wet season, around September onwards. The spotted whistling-duck often chooses to nest in hollow tree trunks, and like other whistling-ducks it is likely to pair for life. However, little else is known about the breeding behaviour of this species (3).
