Birds and reptiles.

Not exactly the best with kids, unless the kids really have a good understanding of how to deal with them. Sometimes it's best to start with one or two pets and let the kids get used to those first. The corn will be great for this. Once the kids understand that these animals are different from dogs or cats, and need special handling, they be able to get along with all kinds of things.

You may even be able to try another macaw some time in the future.
Hope everything goes well. Once your rosy and corn get used to their new home, you'll have a couple of really wonderful pets.
