Good
thought. I had not thought of that. Would seem unlikely but I wouldn't say no.
Who knows, it could be as likely as my suggestions. If the bird could be found
again it shouldn't be too hard to see. The photo shows as just black patches. If
it is a hybrid, I would expect the dark areas to have some aspect of the
distinctive feather pattern of the Straw-necked ibis (which is
barred glossy dark green) rather than just black, but the photo is
not clear enough to show that.
I
remember the almost all black, pelican at Lake Tuggeranong years ago that
gradually returned to normal.

Do
White ibis and Straw-necked ibis ever hybridise? A summer holiday
thought.

I can't tell from the photo if it is a young bird (excess black
on wings and back is not a sign of being a young bird) but assuming the
black is real, it is either exceptionally dirty, has been tampered with by
someone or had a fight with a black paint tin or oil (they do get into
garbage) or has an abnormality of an excess of melanin.

I took
this photo at Lake Jerrabomberra this morning. I have never seen a
juvenile White Ibis so not sure if this is one or a mismarked bird.
Any
thoughts?
