[cobirds] Light Morph Harlan's Hawk - Jeffco

On Friday after visiting Red Rocks, Michael Kiessig, Rob Raker and I visited South Platte Park just north of C470 and the S.Platte River. On the drive over we observed a dark Harlan's Hawk on the west side of C470 between Quincy and Belleview. Most winters there has been a Harlan's seen in this area. At S. Platte Park we observed 9 Greater Scaup in the pond closest to C470 and the S. Platte River. We also got a glimpse of a skittish Harlan's Hawk which appeared to be a light morph. Clean white underneath with a uniform dark back. The head had quite a bit of white in the area of the supercilium and crown, while the tail was a dusky white with just a touch of rufous above the grayish tail band.

Perhaps some of our talented photographers could get some photos of this wary Harlan's, so it could be studied in greater detail. The light morph is very rare among Harlan's.
