Precision flying

Birds initially have trouble flying in enclosed spaces, but our cockatiels have had plenty of practice, and do a little acrobatics show every morning, usually about 10 mins after they get up. Here they are, seeing how close they can fly to the wall without crashing.

Here's Pete, showing off his full set of feathers:
Here's Tom, who's moulting so is missing a few feathers:
In this one, it looks like he's got a bit too close to the wall, and is pulling up hard to avoid it!
And finally, the two of them together (yes, they do sometimes crash into each other, but never very hard):
