"Helicopter surveys for colonial nesting birds on Islands along the Canadian southern Beaufort Sea coast were conducted on June 27 and 28, 1987. Ten Islands were searched by foot yielding 446 Glaucous Gull nests at 7 Islands, 78 Common Eider nests at 8 Islands, 5 King Eider nests at one island, 41 Brant nests at 5 islands, plus a few nests of Sabine's Gulls, Arctic Terns and Oldsquaw. Most of the Glaucous Gulls were at three sites: 249 nests at Escape Reef; 101 nests south of Hooper Island; 66 nests at a small Island northeast of Hutchison Bay. Thirty-one of the Brant nests were at a second small Island northeast of Hutchison Bay. Timing of Glaucous Gull nesting appeared to be more advanced at western colonies than at eastern colonies. Sample sizes for Brant and eiders were not large enough to assess differences in nest initiation throughout the study area. Locations at which no birds or minimal numbers of birds were observed are indicated on maps of the study area"--Abstract, p. i. Issued also in print format. Includes abstract in French.
