观察细节
Dark morph buteo with relatively long wings. Dark wrist patches on the under wing contrasted with paler flight feathers, and slightly less dark under wing coverts. In some angles/light the under wing coverts appeared slightly warm in tone. White bases to the primaries made a pale patch on the upper wing. Tails was heavily barred, appearing nearly completely dark in some angles. A dark sub-terminal band could be seen from above. The head was slightly paler than the body. We picked up the bird hunting along the airport runway and watched it at close range before it was chased off by a Gyrfalcon. A few in our group got photos.
