Yeah, exactly. Some of them are territorial too, and have certain places they just don't like flying, or are scared of, or they can tell there's another Pokemon around that has that area 'claimed'. Territory can be a big problem, though I've noticed that a lot of Pokemon aren't as bad as it as some of the birds back home.

... Braviary? Well... the next time I end up with Rufflet egg, do you want one?
