My Blue Quaker, Skye, is best buddies with my little Budgie, Cloud. (yeah, I know....Skye and Cloud!)
Cloud is a re-homed bird....I got him from a man who could no longer keep him. Skye (also male), I bought when he was 4 months old. He'll be 2 on July 21st. I think Cloud is about 4.
When I first brought Skye home, Cloud was immediately interested. He flew over to check out the newcomer. Soon, these two were hanging out. Now, they play together all the time, talk to each other, groom each other, "kiss" and all kinds of bird things.
