Gang-Gang Cockatoo Community Survey

Lost Cockatoo. Have you seen this bird?

The Gang-gang Cockatoo (Callocephalon fimbriatum) has not been recorded in the Hornsby or Ku-ring-gai Local Government Areas since late 2016. We are worried the population of Gang-gangs, which is listed as endangered under the Threatened Species Conservation Act, has suffered a dramatic decline and is at high risk of extinction. We are asking for your help!
Gang-gangs are likely impacted by a number of factors including loss of habitat, loss of hollow bearing trees, increased urbanisation and potentially the recent arrival of Bell Miners (Manorina melanophrys) to the local area.
Ku-ring-gai Council, Hornsby Council and the Office of Environment & Heritage Saving our Species program are working to find out about recent sightings of both Gang-gangs and Bell Miners in the local area.
This brief survey will give us a clearer idea of what is happening to the population.
