Includes bibliographical references (p. 44-48). "Lack of knowledge of breeding habitat distribution and requirements for the endangeredeastern North American population of Harlequin Ducks (Histrionicus histrionicus) prompted an investigation of a known breeding population in Hebron Fiord, Labrador. Objectives of the study were to: 1) determine which streams are used by Harlequin Ducks and estimate total breeding population in Hebron Fiord; 2) identify habitat requirements for breeding by comparing habitat characteristics and benthic invertebrate species composition between used and unused streams and among strata varying in type and amount of use within a stream; 3) detennine breeding phenology, sex ratio, and proportion of females breeding; 4) compare activity patterns of males, females, and broods, especially the proportion of time devoted to feeding; 5) assess diet; 6) find nests and broods to determine habitat use and behaviour; 7) relate phenology, diet, and activity patterns to within-season changes in stream habitat and benthic fauna; and 8) capture, measure, colour band, and obtain blood for genetic analysis from adults. The study was conducted from 8 June to 14 August 1996"--Summary, p. 1. Also available in print format. Includes summary in French. gccst Ecosystems gccst Aquatic birds Rodway, Michael S. Canada.
