I agree, he looks pretty normal to me. He's just a little boy, give him some time!

None of my Columbians have bumps on their noses, but then, none of mine are rubbing to get out, either. I wonder if these Columbians you are looking at are true red tail Columbians? Just because you keep referencing the longer noses, which are more typical of the true red tails (I think it makes them look more regal).
