Hi. Ever since I began feeding my budgies treats between the bars of the cage, they have began going wild for it. I usually take them out to feed them, but its been getting cold these days so they stay inside now. Anyway, now, whenever I'm in the room they're in, they begin chirping to me and trying to climb to me. Whenever I try to perch them now, they always bite my finger. This never used to happen. How can I make them stop?
Biting is a hard habit to break. I’m going through the same thing with my little girl, so I understand what you’re going through. It sounds like your budgies are enjoying spending time with you and are wanting to be with you, which is why I think they’re chirping and climbing on you. Maybe the biting could be that the bird doesn’t want to be put back into his/her cage? As for stopping the behaviour, there’s really no set method for getting a budgie to stop biting, but working out why they are biting is a good start. (Eg. if the bird is biting when you try to touch it, it doesn’t want to be touched). My girl doesn’t bite out of anger. She’s just using her beak to test things and it happens to hurt. Never punish a budgie for biting (or for any reason) as they don’t understand and it’s unfair. Try redirecting his/her attention. Often refocusing them helps.
