I am birdysitting this weekend

[CKD]

My dad brought over his tiel last night for me to watch over the weekend. It is about 6 months old now. It is a white face with pearl markings. I really dont know much about the different breeds of the Tiels. All I know is that my Chopper is a male pied.
If I were to post some pics of my dads tiel could you tell me what type it is and maybe what sex it is ? If You can tell me the sex by a pic is there a certain part I need to take a pic of ?

Sounds like possibly a female with the pearls though males usually don't loose their pearls till they are 1 1/2 to 2 years old. It might be possible to tell the sex by a picture, though as far as pearls go, it may be harder or easier if the bird has been going through a molt since hatching. Females of course keep pearls, most males loose pearls...

Indeed, whiteface tiels do not have the orange patches. The males have a clear white face, while females have a mottled grey face with white patches.
