Out of curiosity, after another friend questioned Willy's sex, Helen just went to Ask Jeeves and found pictures of a male vs a female. That female sure looked alot like Willy!!
Here's a quote:
For normal greys, cinnamons, and pearls, adult males and adult females are easy to tell apart. The male bird will have a bright yellow facial mask that covers most of the face, surrounding the orange cheek patch. Both sexes have the orange cheek patch, but the hen's is duller. For whitefaces, the adult male has a bright white facial mask; the hen has a slight mask that is a lighter gray but not the pure white of the male's. Whitefaces do not have an orange cheek patch, or any yellow markings.
Willy/Wilma is dull.....beautiful, but dull. Wish I could show you the picture, but it is on a Geocities website and I don't think we can link to there.
The hen has a fuller, wider chest than the male. Yep!
The male's crest is longer and more curved than the hen's. Yep!
I'm going to attach a picture of a female who looks very much like our Willy. And then we're going to start thinking up a new name for our new bird. A feminine one.
