Enzo LOVES to fly, and i must say, she is a very good flier. In the UK houses are a lot smaller that in the states (and hugely more expensive!!) so she has less 'open space' to fly so more acrobatics come into play with her. For instance, my hall way is maybe 4 foot wide by the door, she can fly at normal speed , stop,turn around and fly back pretty much within her wingspan..... it always impresses me that.
The big problem with a parrot that has unrestricted access to our house is chewing, if it can be shredded, it will.... door frames, bannisters, curtain poles, curtains, beds, towels, you get the idea. Im on first name terms with the local joiner as im putting his kids trough college.
Get a slow motion video of him, you will be amazed at the flight and how much goes on taking off, flying,turning and mostly the stopping/landing. Those wings too, pretty big for a relatively small bird, Enzo shakes her tail feathers like crazy in flight but it seems its out of enjoyment rather than actually steering her.
One more thing about flight in the house, try and get him to fly down stairs as much as possible, he will likely not want to at the beginning, Enzo hated doing it and would only fly down if I rustled the packet of her favourite treet in the kitchen whilst i excitedly call her. Now she flies up and down quite happily. A very useful skill if she flies away, goes to the top of a tree and is scared to fly down again.
