The cormorant has probably been foraging in water which was badly
rust-stained. This stain can be natural - I have seen it on fresh and
salt-water. It looks rather like an oil-slick but doesn't seem to affect
the birds' flying ability. The stain seems to lessen and be lost when
they are in clean water.
The cormorant is certainly very stained indeed.

I see a lot of birds with staining down on the Bellerine Peninsula in
Southern Victoria....especially at roost at Lake Lorne for some reason,
(less so at other coastal and inland roosts)
The bird pictured on birdline however is a pretty extreme case. I always
thought it was some type of marine spawn or something. But looking at
that photo gave me a brain wave...i wonder if cormorants go for squid's
and get inked???

[Birding-Aus] Stained Little Pied Cormorant
Hi all,
On Birdline Victoria at the moment is a photo of a Little Pied Cormorant
with a remarkable amount of staining on its "white" plumage.
You can find it at www.eremaea.com and click the birdline Victoria link.
Anyone know how a bird could end up like this?
Simon Starr.
