观察细节

Unexpected (presumably wintering nearby). Dark morph adult relatively low and heading S directly over boat launch. Slim, long-winged buteo almost entirely dark below minus whitish undertail coverts and rufous barring on flanks and underwing coverts. Flight harrier-like with buoyant wing beats and pronounced dihedral when gliding. Photos.
