| Summary: | Reports a survey in a mountain valley at 67 N. on eastern Baffin during the 1953 Arctic Institute expedition. Some 389 adult birds of eight species were counted in a square-mile study area in mid-June; density varied with habitat, being greatest on wet grassy and sedgy flats; comparisons are made with three other arctic bird counts. Breeding success, 60 % for passerine birds, was estimated by counting nests and fledged broods in July. |
