Someone asked me if adult female Northern Harriers have a plumage that coincides with their eye color. In other words, do yellow-eyed adults look different than darker-eyed adults? And the short answer is no, adult females can look rufous washed underneath, buffy washed, heavily streaked, or lightly streaked, at any age of their adulthood (or with any eye color), below is a few examples ("click" on images to enlarge). 

And, it takes a few years for females to get the lemon-yellow eye that adult males have. Is it possible that a certain plumage is more common than another -- of course, but that is irrelevant to this issue. Thanks for the questions and hope I can answer them as they come…
