"March 1988." Includes bibliographical references (pages 129-134). "Information pertaining to avian distribution and abundance along the Canadian Beaufort Sea coast was summarized and used to evaluate the importance of the coastline to birds, in a regional context. Seasonal differences in the requirements of birds were considered through separate evaluations in each of four time-periods: spring migration (May to mid-June), nesting (June to mid-July), molting/broodrearing (mid-July to mid-August), and fall migration (mid-August to late September). The evaluations are presented in a series of ten maps as colour-coded delineations of regions of high, moderate, variable and low avian use. For each region in each time period there is a description of the major aspects of avian use (which may include comments on local population estimates, behaviour, year to year variation in numbers, and local movements of birds), and a listing of some of the data used in the evaluations. A general discussion on the limitations of the data used is presented in the introductory sections as an aid to the interpretation of information contained in the report"--Abstract, page i. gccst Aquatic birds gccst Nature conservation Canada.
