Catoctin Wildlife Preserve - Australia Aviary - Western crowned pigeon, golden pheasant, Mandarin duck inc. albino, paradise shelduck (?)

Looks like a female Paradise Shelduck (Tadorna variegata) to me.

@WhistlingKite24 Thank you! Only the sun conures (on the ceiling) were signed, and it's a species I haven't seen before.

Yeah it is a normal female Paradise Duck in the front.

The Golden Pheasants are mutations - and the male one at the back is a hybrid with a Lady Amherst's Pheasant.

The white duck on the platform is a white mutation of Mandarin Duck.

@Chlidonias thanks! I was wondering about the color of that pheasant but I didn't know what to look for.
