Onan, from the Book of Genesis, I name all my birds Onan.
That said, I think the name “Allied/Signal” for a highly vocal cockatiel could be interesting and fun 
This is so very wrong.
I’m using it for my next boid.
Tom O’Bedlam. I always figured that’d be a perfect name for a psittacine, screechy, lunatic ( but still lovable ) critters that they are :).
Oh, yeah - video.
Conrad Twitty.
Aaaaagh! to think that I had to spend two minutes on whether I’d name mine Gudrun Ensslin or Sadie Mae Glutz.
Sadie won out. Some animals just look like a Sadie.
I think I’m going to take Beaker for mine. He’s one of my favorite muppets. I never really named the two Quakers so I think I’ll call them Bunsen and Honeydew.
Are you sure what gender it is? It’s hard to tell when they’re young.
When I was a kid I showed my sister a picture of Led Zep and asked her “Whose this chick standing by Robert Plant?”
My sister just looked at me funny and said “That’s Jimmy Page.”
So years later when I had a cockatiel whose gender I couldn’t determine I just called the thing Jimmy Page.
Cockatoo!
Of course then there is the classic pet name, “Guess.”
Irving.
