It is known that adult Harlan's Red-tails often have unbanded, mottled, or a mix of unbanded/banded remiges (primaries and secondaries), but of course there are exceptions to EVERY rule. Here are a few Red-tails that show varying degrees of banding to the remiges. The first 3 are adult Eastern Red-tails (the 2nd bird shows several Krider's traits). The 4th bird is a juvenile Western that also had a tail pattern simlar to the remiges (broken bands that create a mottled effect). The last 2 are adult Harlan's for comparison. Just thought I'd show these for future reference...I have a bunch of examples from my own collection, but it is valuable to show that others are documenting this stuff too. Collaboration is important!
