I have a question re: Harlan's and Krider's morphs of the Red-Tailed Hawk.? I remember several years ago, I was on an Audubon field trip in Mason County, and we saw a hawk which was difficult to identify, but we eventually concluded it was a "pale-morph Red-Tail," to use the guide's term.? He did not call it a Krider's, even though Krider's is a pale-morph Red-Tailed.
So my question is, is it proper to use the term Harlan's for every dark morph, and Krider's for every pale morph, or are these forms more specific than that?

Great raptors at Wylie Slough this afternoon. ??Both Sharp Shinned and Coopers, Red Tail, Harrier, Eagles, Peregrine and Rough Legged (just before WMA) but highlight was a very dark Harlan's Hawk. ?? Gorgeous bird.
