Notes:

The Pacific Black Duck is probably the most known of Australian ducks and can be found throughout most of Australia, being absent from the arid desert interior of Western Australia, South Australia and the Northern Territory. It can be found in a variety of habitats including wetlands, ponds, streams, marine waters, farm dams and parks. It prefers areas where there are large permanent water courses with plentiful vegetation. The Pacific Black spends most of its day foraging for plant and animal food in the water, such as seeds and shoots of aquatic grasses, millet and yabbies. Young ducklings eat mostly aquatic insects. It is sometimes a nomadic bird, following rain and floods but will remain sedentary in areas with plentiful water. Breeding is timed to occur when water areas are at the most extensive and aquatic food is mature. In the south the breeding period is around June to January and from January to April in the north. Those living in semi-arid areas breed anytime in the year after good rain. Preferred nesting sites are made in tree hollows, high off the ground however nests will also be made on the ground hidden in dense undergrowth. Between 7 and 12 eggs are laid and incubation is by the female for a period of approximately 26 to 30 days.
