my bird looks extremley like the bird described as (as well as the bird on the second page):
Heavier marked Pearl on more extensive Cinnamon ground color
so I'm guessing s/he is heavier marked is all and there are variants, either way she definitely has cinnamon colouring (or at least not the usual grey shade and she certainly has pearls)
you can't really tell gender from looks,since mutation females rae brightly coloured as well
this bird still confuses me because he does not have a whistley chirp, but a harsh one like a female but he also tries to copy tunes in chirps rather than whistles so no idea whats going on with this bird to be honest!
