Phi.......... too bad you don't have a dorsal shot of the bird, especially the
tail. It is not a true Krider's by any means. It may have some Krider's
genetics based on the very light tail. Intermediates occur on a regular basis.
Krider's are not rare in Wisconsin. Up here in the northeast they made up over
5% of the immatures trapped in autumn migration. Numbers should increase
westward across the state and especially down in the southwest. Their main
migration route appears to be down the Missouri River valley but winds drift
them east to Wisconsin. They should be expected in both spring and autumn
migration, especially in fall. The rest of the ventral view of this hawk
appears to be a regular Red-tail.

On 03-01-2010 a hawk was circling near enough to manage a close
photograph. When I sent a copy to Pat Ready he thought it might be a
Krider's.
Check out the link below to see if you can identify this hawk. Pat said
it very Rarerare to see the Krider's in Wisconsin.
