Basically, I have the chance to adopt a 4 year old military macaw, who, if his owner described him/her correctly, is very friendly and hand-tamed. The only problem is that this bird is about 4 hours away. If I do actually get to adopt him, what should I use to transport him? obviously I'm not going to just throw him in a cardboard box for 4 hours. I've heard about travel cages but I don't know what they are, just a small cage that fits easily into the back seat of a car?

Also, if anyone else has any other tips for keeping birds calm on a 4 hour car trip that would be great. I know it'll be hard to keep a large bird in a small space for 4 hours and I'd like to keep the stress level as low as possible.
