The male blackbirds here evole their song year by year.This sharpens the upcoming males to improve .The older bird gets first pickings.Only an accident will let a whipper snapper mate.Then its back to basics.
My blackbirds are very tame.Come to hand for sultanas.The mother has taught her babies to do this.We weaned them year by year because there were too many.The balance of nature was upset due to us fostering a young female.
