You can help our research by reporting sightings of marked & unmarked cockatoos and their behaviours using the new Big City Birds app! Check out www.spotteron.com/bigcitybirds to get involved! @Big_City_Birds @wingtags @sydneyscience @australianmuseum @rbgsydney #forthewild #bigcitybirds #clevercockieproject #wingtags #sulphurcrestedcockatoo #nationalbirdweek」10月19日 8時30分
