5 Mo old Congo African Grey (genetic red mutation)

by Zana
(San Diego)

I just bought my Congo yesterday from the aviary. Fresh from the nursery. (they dont sell them unless weaned and perched) He's got allot of red scalloping on his sides and under his chest and a light pinkish color to his wings. Very handsome bird. Eyes are still gray in color, due to age.

My question is, is this common for a genetic mutated bird to have a pink & black camo tongue? Does this mean he will keep his red scallops after his first moulting?
Or will his tongue darken all the way once he's matured?

(I am not new to having exotic birds, Since I got him x-mas eve, today being x-mas, he's not been into the vet for a well check up. But the aviary is known for selling birds with outstanding health, so I am not worried that he is sick, no worries, I have a great avian vet he will go to!) Just want to know if this is common with mutations, and if it means he will keep his beautiful red!

All my birds have been 3+ yrs and older. "Butters" (as the kids call him) is my second african grey (Actually 1/4 birds). He's just the first to be genetically mutated.

Due to age as well, Being he's my youngest, Any tips would be apr in helping with his begining training. (no snide remarks please!)

Thank you!
