Gang-gang Diet – New Study

A new study published by the Australian Burd Study Association (ABSA) found that the diet of Gang-gang Cockatoos is broad and flexible and their food is abundant. Over 4,000 feeding records from across the species’ range were collated from image-based records posted on social media and citizen science platforms, and from the written records of bird observer clubs and bird group databases.

A total of 275 different food items were recorded in 7 main groups:

  • eucalypt nuts and flowers (43% of all feeding events);
  • berries with relatively large seeds but a small pulp mass (21%);
  • green cones of mainly the Pinaceae and Cupressaceae families (10%);
  • wattles, almost exclusively in spring – early summer and on plants with green pods (8%);
  • soft pods mainly of Liquidamber Liquidamber styraciflua (7%);
  • nuts, mainly walnuts Juglans sp. and oak acorns Quercus sp. (3%), and
  • invertebrates, mainly sawfly Pergidae sp. larvae and lerps Pysllidae sp. (1%).
