This amazing video of parrots playing basketball is fascinating watching because it shows the results of patience combined with excellent animal training techniques. This video shows clips from "1 on 1" and "2 on 2" basketball games, starring parrots, Bo and Yoda (Congo African Grey parrots, Psittacus erithacus erithacus) and Hannah and Gustav (Solomon Islands Eclectus parrots, Eclectus roratus solomonensis).
Wow. That's incredible. My birds that /get along/ nip and bite at each other all the time, so for her to have gotten four birds to work together like this and wrestle over the ball without bloodshed is downright miraculous.
