I am wondering about the advisability of buying a 3 year old white capped male pionus from a pet store -he has been there for 1 year and has regular beak and nail trims-I recognized the breeder who I think is ok-my parrot experience is limited to budgies and cockateils as a child- he seems a bit "cage aggressive" but stepped up and sat without problems on my hand-he comes with a health guarantee Thanks for any advise
