I have a two yr old male Red Rump Parakeet. I was told that you don't hear their beautiful "singing" when you only have a single bird. I don't want to raise babies therefore do not want a female with him. My question is: can I get another MALE Red Rump as a cage mate for him. I was told by a breeder that I could, but have read conflicting statements on this. Does anyone know if two male Red Rumps can happily/peacefully be cage mates?
