We were worried about how they'd react to each other, but they were fast friends right away, though Otis, being a giant pacifist, did let Marvin push him around a lot.
We had to have Otis put to sleep this summer, so then we got Wilson. Again, it was love as soon as we put Wilson in the cage - all kisses and cooing. I think they're even more attached to one another than Marvin and Otis were, which really surprises me. Plus, the relationship is much more equal, which is nice, but it also means that we have to break up more tussles.
I have heard that there can be aggression problems, esp. with bigger birds, but I haven't seen it yet. As I'm sure you've already noticed, birds have surprisingly strong, highly individualized personalities,* so you kind of have to watch your bird and judge what'll work for her.
* - Took Otis to the vet once; had to fill out a form with basic information about him. I got to the question in which I was asked to describe his personality and it actually gave me pause. A parakeet weighs less than a roll of Lifesavers and I was considering using the word "witty." Jesus.
