Includes bibliographical references. "This collection of papers derives from a symposium held at Memorial University of Newfoundland, St. John's, in April 1989. Contributions by Evans and Kampp and by Kampp deal with the current dynamics of the Thick-billed Murre population in West Greenland. Evans and Kampp provide clear evidence of a substantial decline in numbers over the past 50 years. Kampp's detailed analysis of band recoveries points to shooting at breeding colonies as a major cause of mortality, and one that affects the most demographically valuable segment of the population - the breeders. He also examines the weaknesses of haphazard banding in attempting to answer certain demographic questions"--Introd. Includes abstracts in French. gccst Aquatic birds gccst Ecology Gaston, A. J.
