Great find. It looks like the legs as well as the bill are
atypicallybright and somewhat shifted toward orange, so something odd
may be going on with diet or possibly enzyme release affecting the
bare parts. The occasional Western or other species will showsimilarly
hyper-colored/orangeish bare parts
It also appears to have a largely dark or possibly damaged rightiris
even though the left appears typical.
