Little Egrets are quite interesting, so definitely worth discussion. I have
a photo of a nominate bird from the Leanyer Sewage Ponds on my ntbirds
website:
http://ntbirds.net/gallery/displayimage.php?album=search&cat=0&pos=3
Generally, they have similar feet in all stages, breeding, non-breeding,
though the contrast is less in immatures and non-breeding as the legs are
less black and the feet a little less yellow. The facial skin is always
bluer/greener than on our local birds but generally this too is duller in
non-breeding, just like the yellow/pink on our birds is less intense in
non-breeding.

Of more interest to me at the moment is foot colour of the local race. It
seems that the soles of the feet in breeding birds in the top end are
either entirely black or have so little yellow as to make it impossible to
see even with good views. Any comments on that - is it the same with
southern birds? Or is it just one of those very variable things, and I just
never get to see the ones with yellow soles. In non-breeding the soles are
yellowish, sometimes almost the whole foot is yellowish or at least pale,
with yellow-pale often running extensively up the back of the leg,
sometimes quite sharply in contrast with the rest of the leg colour.
