My budgies have learned to get onto a perch, but it only works inside the cage. Outside the cage, my budgies simply fly away from the perch if I put it next to them. I am not sure what to do, and they are unclipped. I think the only reason they go on the perch is that I am pretty persistent with them and outside the cage that doesn't work because they can simply fly off. They also can eat food from my hand, but again it only works inside. If I try to hand-feed them outside their cage, they will just fly of.
