What bird to buy as a companion for my Cockatiel?
I’m a long-time pet lover. I got a baby Cockatiel 2-years ago when I decided to have my own pet bird. I chose Cockatiel from other bigger parrots since I was a first-time bird owner. Its been 2 years now, and I would like to upgrade to a bigger bird. I plan on keeping them in different cages. What all options do I have? or Should I once again go with another Cockatiel?
