Stop Brexit!
So far 11 Cockatiels, 10 Budgies and 2 Canaries (if my maths are right), must say I'm surprised at the ratios, thinking that Canaries would have been lying 2nd and Cockatiels not even in the first three!
Cockatiels are more intelligent, and have stronger bills than most other cagebirds, = greater will to escape, and greater ability to carry it out?
