Harrier Eye Color

on Monday, December 9, 2013 

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 comeā€¦

Definitely a useful post. Thanks for posting so many photos. I bet you have the largest harrier photo collection out of anyone. Love to see it.

I do have thousands of flight shots. But more interesting to you Bryce is I have a lot of in-hand birds too, caught 16 adult males in ONE DAY in 1996 at Braddock Bay, so my collection is huge, but who knows about the most?

Neat pictures, I was unaware of this female variability, and enjoyed your Birding article on the adult males. Can you make a post about the juvenile plumages Jerry?

Neat, I haven't seen those orange breasted females here in CT. I know I would have called those juveniles if they went overhead at my hawkwatch (Lighthouse Point). Is that a Western thing?

Yes, a Western thing for the most part, but not completely. I've blogged about it but not sure when. A search of my blog in the search tool will probably bring it up

That one photo of the bird banking to the right with it's mouth open and the tip of its primaries just skimming the water is great! That would be a heck of a poster, even for guys like me who don't care too much about harriers.
