What type of cockatiel are there?

Just wanted to know

Those are two different cockatiels just to clear up any confusion

 

[Rosa moschata]

The first appears to be Cinnamon-Pearl. If it's older than a year, it's a female.

The second appears to be a Pearl male in the process of molting into his un-pearled adult plumage, which happens at between 6 and 12 months of age. He will always be genetically Pearl, but males lose the markings as their feathers darken at maturity.
