There was a group of about 4 of them closer together and just eating seeds from the grass.
I’m assuming they’re owned by someone nearby? I dont know if cockatoos just walk around on the ground in their natural habitat.
No, they’re wild. They might have some places they regularly visit for food where people live that put out sunflower seeds or similar bird feed.
It was an open park and they would have been able to see any cats or similar approaching. Even if I got closer than say 5 meters, they’d walk or fly away.
What country are you from? In suburban Melbourne, Australia, I regularly see wild sulphur-crested cockatoos, galahs, rainbow lorikeets (ok not cockatoos, but they are parrots), and occasionally gang-gangs. Flying around, in trees, in parks and gardens. I’d be surprised if most places in Australia didn’t regularly see wild cockatoos.
Do other countries have wild parrots and/or cockatoos?
