All the pet birds I have had in the past have to go through the ritual of flying into glass windows or walls at some stage.
It’s harrowing when it happens, but they never seem to properly injure themselves. They just look a bit perturbed for a minute or two.
This is Oliver, I’ve been looking after him for a few weeks, he’s been pretty badly neglected by his owner for the last 18 years.
Vicious and wary when he first arrived at mine, but now as you can see, his inherent tameness seems to be slowly resurfacing.
