I think it's some kind of duck... They take off as soon as they see me so I can't get a photo. Both are black with tiny barely noticeable white feathers at the wind. One... I figure is the male has a 1 inch to 2 inch patch of Red under the eye. I've searched photos and none of them has a bird with red under the eye. They are waterfowl because they are hanging out in the creek behind my warehouse with some mallards. I'm in Portland Oregon. Thanks Kelly
