My guess is he is a Beautiful tiel normal colored WF tiel!!!!

Well Im assuming he's a male, how old is he? if he keeps he's white face after his first/sencond molts then he is definitely a male. female whitefaced tiels will have a solid grey face.

my female cinnamon tiel still has a whiteface but it's because she is a heavy pearl, pied. she was DNA sexed and also she laid eggs. I also have a normal WF female tiel, her face is grey.

Sounds complex but it really isnt.

The WF mutations are my fave!

good luck with him!

PS
males are also the talkers & whistlers. females can do it a little but usually its the males! my cinny wf pearl pied girl wolf whistles, but thats about it. so if yours is talking and saying words, thats another good indicator that he's a boy!
