Well, a
Roc bird is a mythological gigantic bird (Indian mythology or Middle Eastern, I can't remember), so maybe
Rocco if it's a boy would be a nice name for a parrot.
Years ago, on a show here called Burkes Backyard, a budgie won the talking budgie competition, and his name was Juicer, which I really like for a bird too.
Other names;
Rudy - my beloved (long deceased though now) birds name.
OttoQueenieTrinny
Aello (name of a Harpy in Greek Mythology)
Ocypete (Ok-sip-it-tee), also a Harpy.
Have fun with your new bird, they are wonderful pets, lucky you!
