I put my finches in the aviary and a male is showing aggression to the other birds if they come near his perch or female friend is that a sign of domanece? or claming terroirtorry and he even had a go at the last gouldian and they are make werid nosies the males are doing like a growl and moves closer to his mate? whats this is it a sign of breeding?
any help would be great and my plan is to breed in the next 2 weeks or next week when i feel that i am ready
