I have a cockatiel, he just turned 1 and his name is Colonel Crumpet. Hes well with other birds as my gf has 3 of her own, a fiery shouldered conure, a turquoise conure, and a parakeet. Him and the turquoise have grown close as of recently. I have to move away from them and the tiel is coming with me, im concerned without the turquoise he might get sad/depressed. I was wondering if a pigeon would make a good companion for him, if i needed to get another bird.
