Studies of waterfowl (Anatidae) in north Queensland. 3. Harvests

Abstract

The total harvest of waterfowl by shooting in north Queensland during 1963 was an estimated 70,000 birds. At all times and in most localities the preferred black duck (Anas superciliosa rogersi Mathews) was the species taken, predominantly because of habits, availability including accessibility, and suitability as sport and food. Harvesting was assessed to have had no effect on the total black duck population in north Queensland because of proportions taken and numbers remaining, and species' and shooters' habits. Other species were taken only secondarily in small numbers and, with the possible exception of vagrant species, in small proportions.
During 1952-1963 total annual harvests varied greatly, from none in years of extreme drought and flooding to 100,000-150,000 birds in years immediately following widespread flooding when populations were largest and dispersed.
