Cogswell 1949 Buteo regalis Dec. 11. mi. SE Hustine, Merced Co., Calif. Two individuals, both in light phase, were soaring at a height of 250-300 ft. over fields & marshes of SE part of Hustine Land & Cattle Co. (Club 14) land. one of them came close enough to us so that we saw the dark shank feathers of the adult, and the double row of dark spots on the (tips?) of the underlying coverts -- the rest of the underlying surface being almost entirely white. The base of the tail in both birds was white, gradually becoming slightly darker until the terminal strip band was definitely brown. They both showed white "flashes" at the base of the primaries also. In comparison with the many red-tails seen today, the rough legs also had a noticeably longer tail & narrower (longer?) wings.
