And, if anyone was wondering...yes, Krider's do make it to Florida and the gulf states every year in fair numbers, and in Texas and Oklahoma in large numbers. This bird has a pale head and looks to have a fully reddish tail, but within the range of what we call Krider's for sure. And check out the dark malar that many Krider's (adults and juveniles) show.

Neat looking, without any belly band at all, cool posting.

Very close to a Fuertes.
Hi Hatem
That is one of the things....Krider's and fuertes can be very similar and they are straight north/south of each other in the same habitat that connects so my feeling is the plains birds are related and it is likely fuertes is not a true race, but a form of borealis like Krider's. I have seen birds breeing in ND that look just like fuertes and pics of birds from OK that near Krider's but not quite. But Fuertes is really non-migratory and Krider's is highly migratory so adult birds especially that show up in winter out of range for fuertes and loo like Krider's are Kriders. And birds identical to this breed throughout the northern Great Plains.
I asked birders/photographers via a listserv to be on the lookout for this hawk, hoping we can get a good photo in favorable light conditions and a topside image. That lack of any meaningful mark on the patagium really threw me a curve at first, especially here in Short-tailed Hawk country. I sure hope we can get more photos.
Makes perfect sense, Jerry. It's scary the physical similarity between those two such as this when you have the plain belly and even the light patagials (although the Fuertes does seem to have heavier or darker patagials even the super light ones, but the ones on this bird are barely visible) but when you break it down geographically like you did so well it makes a ton of sense. A very similar situation to the Kriders that look almost identical to light morph Harlan's.
Very interesting theory Jerry, Fuertes and Krider's. Is there any good source on Fuertes out there, description and/or pictures?
My friend Jim Lish lives in OK and has been documenting and studying fuertes for years and years. He published a fuertes paper years ago, I'll see if I can dig it up. He might have a site with photos, I'll check. He has shared thousands of photos with me over the years, is extremely knowledgeable, and a great guy.
