(Gregory James), 1970- Breeding seabird populations in Groswater Bay, Labrador, 1978 and 2002 [electronic resource] / Gregory J. Robertson, Richard D. Elliot and Keith G. Chaulk. [Mount Pearl, N.L.] : Canadian Wildlife Service, Atlantic Region, 2002. iii, 31 p. : ill., maps Canadian Wildlife Service technical report series ; no. 394 Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographical references (p. 11-13). "Little information exists on the population size and trends of seabirds breeding in Labrador. To date, the only information on breeding population trends comes from the Gannet Islands south of Groswater Bay (Robertson and Elliot 2002a). This report presents population size estimates for breeding seabirds in six small colonies in northern Groswater Bay based on surveys conducted by GJR and KC from 21 - 27 July 2002, and compares them to estimates from a similar survey conducted by RDE and Remi Odense from 3 - 26 August 1978 (Elliot 1978). 1978 was a particularly late breeding year for all species, with significant amounts of pack ice still present in early July (Birkhead 1993), while 2002 appeared to be an average season in terms of timing. Further, we compare trends in seabird numbers in northern Groswater Bay with those in the Gannet Islands, to assess whether trends in that large colony are representative of seabird breeding populations in Labrador. We also present incidental observations of other bird species, including counts of moulting Harlequin Ducks (Histrionicus histrionicus), a federally- and provincially-listed species of special concern"--Introd., p. 1.
