I have found that the Brandt's Cormorant has blue eyes. Double-crested Cormorants have green eyes. I think I have seen pictures of one with red eyes, what kind would it be?
That might be an Anhinga which looks somewhat like a Cormorant. It has silvery white coverts and a longer tail than Cormorants. The neck is also longer. The bill is more like a heron's bill rather than a Cormorant's.
