Tom, those Swainson's that flew over my house and the north Glendora foothills were ~75% dark phase, ~25% light phase. The light must have been a little better in Glendora. I left the California Botanical Gardens in Claremont a little more than an hour ago. There was a very low flying kettle of 14 Swainson's over Foothill Blvd in Claremont. 3 or 4 of those were light phase, the rest, of course, were dark phase. Those hawks, interestingly, streamed off to the southwest.
