(source - worked at a raptor conservancy). It depends on which bird. Some are really smart and can learn tricks (e.g. retrieving specific objects) for food rewards. They can work out simple puzzles, such as finding food hidden under sliding blocks. Crested Caracaras are examples in my experience.

Others are much less intelligent, in particular owls, who aren't particularly wise. They have great instinctive behaviours but can't solve puzzles. This is partly because, for their vision, a lot of their skull is filled with eye rather than brain - owl eyes are tubular rather than eyeballs and can't move in their sockets, hence the 270 degree neck turning.
