Whoever said Bourke's Parrots are timid and without aggression obviously hasn't bred enough!
This is the worst case of Bourke aggression I have had. I have removed the guilty male which now leaves 2 females & 1 male in the aviary (pity Whistler doesn't have any interest in girls atm).
I had been missing a boy for 2 days but thought he was in with the hen. I couldn't stand not knowing any longer so went in search of him.
I found him:
Please pray he makes it. He is a strong robust bird (normally). I put some disinfectant on his wounds (actually I held him and mum did it) and put some Spark in his water and held it to him while he had a big drink.
