Have you ever had an issue of your birbs flying into walls or windows? My birb would always fly into the wall and fall.

I have had Percy jump into window glass once. And she “flew” into a door once. 

I actually keep their wings trimmed. We have so many big windows and ceiling fans that I can’t safely let them fly around.

Someone with flighted birds can probably help you more, I don’t know how common birds flying into walls is, might just get better with practice.

Good luck!
