This unhappy baby probably tried to fly and fell out of the nest.
He still cannot fly so would not survive on his own.
After speaking to the wildlife rescue service we have put him in a cage next to our wild bird feed table. The adult birds visit him every day and he "talks" to them.
We hope he will be able to fly in about 3 weeks and will rejoin his flock.
If he is injured and unable to be released he will go to the wild life lady.
She has a cage of galahs that have had injuries and cannot be released so he would have company.
