Thanks to all who have provided records for the citizen science Gang-gang diet and nesting ecology studies, We have considerably expanded what is known about the Gang-gang and have informed many conservation and planning actions. A summary of the Gang-gang diet report and a link to the full report can be read and accessed at the bottom of this page: http://redhillregenerators.org.au/?page_id=277

The page also has a summary of the outcomes to date from the nest hollow citizen science research. This project is on-going. From August till mid October is when Gang-gangs are most noisy and active in their search for a nesting hollow so it is a good time to keep an eye out for any Gang-gang activity in or near a hollow. If you could report (via a Naturemapr sighting) any such activity that would be fantastic. The Red Hill Regenerator site also has a link to a guide to Gang-gang nesting behaviour which gives clues as to what to watch out for at the beginning and as the breeding season progresses.
