Tasmanian birdwatchers are being alerted to a serious threat to one of the state’s best-loved ducks. The Pacific black duck is losing the unique character that defines it by inter-breeding with a duck from Eurasia, the mallard. The black duck of Australasia (Anas superciliosa) is the common species that frequents all types of water, from city parks, to isolated forest pools and tidal mudflats.

With an anguished squawk, a white-faced heron let it be known it was not happy. It took flight on lanky wings as its feeding ground on the lower Sandy Bay Rivulet was invaded by a noisy, eager bunch of university students.
