I was camped at my property in Majors Creek last week and had a fun time watching the gang-gang cockatoos eating the hawthorn berries. The trees were full of them, all cracking open the berries and eating the centre. They did this all day! I was ignored as I walked around taking photos of them. I've been told that as the berries ferment the gang-gangs get tipsy. I suspect they were beginning to experience that as I watched them. The morning I left they were screeching and it reminded me of someone with a hangover.... The one in the photo here is male. The female has a gray head with a gray tuft.
