Gymnorhinus 1948 Duck Hawk? 2 27 Aug Hollabam Bay Alaska 005 T, 1.9 mi from Bar Light The hawk heretofore mentioned was seen emerging from the top of gliding the conifer wood, in the pos- tion. It assumed a gliding angle of descent 10° and maintained this glide in the straightest, steadiest and truly most beautiful glide I have ever seen bird make. It did not make the slightest motion (other than the glide) until it broke the glide to swoop down on a flock of sand pipers at the water's edge. When it was, perhaps 20 feet from them. It did not make a catch, and proceeded to chase one of the small bird. Made 3-4 passes at it then abandoned the chase & returned to the tops of the conifers. From top of conifers where glide began to the water's edge where glide was broken was about 400 yds.
