429 Gulnne Duck HAWK (D) 1931 the hawk was avoided by a quick turn in flight on the part of the duck & Harlequin. These ducks evidently reside on the rocky islands and sea cliffs along the Straits. In flight they seem to labor to some extent and their gliders are short but when they plunge in a strike, their motion is incredibly swift. One wonders where or how this can muster such momentum and speed in so short a time and apparently out of nothing. Their color seems to be dark grayish brown with a faint mottling. Oct. 31 Unmak Pass, E. Aleutian Is. About 2:00 P.M. today, while we were in the middle of the pass heading South on board The Northland, a Duck Hawk flew very close over the boat. In a half a minute it hovered over the boat duck and then flew off. We were about 3 miles from land & probably the hawk was hunting sea birds in the pass.
