A Trip to the Park with Parrots

One question I've been getting a lot is about training a dog to come when called. In this video about the West Wings Free Flight Club, a club organized to provide enrichment for parrots through free flight, parrot owner and amateur trainer Neena Lynne McNulty discusses their technique for recall training:

If you want to have a... successful relationship with a parrot, you better be somewhat of a trainer, and understand how you act is going to determine how the bird acts. 
I just spend a little bit of time every day working with my birds to improve the relationship. You call them to come to you, they come, and you provide the positive reinforcement.

They're very trainable. All you need to need to use is positive reinforcement and you'll be a magnet to them."
