Stretched out in the pool on Sunday in a balmy summers 42c I watched the local birds behaviour around the dogs water bowl. I cant say it was intentional, but it seemed to me that one bird would fly in, attract the attention of our dog & the two would then go tearing off down the garden. Following which the water bowl would then be instantly swamped by a horde of birds..... when the dog came back, away they all go.... two minutes later another solitary bird comes along and it all repeats again.
So I certainly wouldn't put it past the buggers from learning to use fire as well. Cockatoo's can shred a camper van/tent very quickly in order to get to food - even if they cant see it. They know there is likely to be some inside.
