Are these birds rescues or is it important for research to observe from birth?


Hi Emily,

Alex came from a pet store and was ~ 13 months when I purchased him; the other birds were generally younger and came from breeders. I do work with one bird–owned by a colleague–who is a rescue…we do cognitive but not communication studies with that bird, and there’s really little or no difference between his behavior and that of the others.

Thank you,
