Observations of harlequin ducks, other waterfowl, and raptors in Labrador, 1987-92 / R. Ian Goudie, D. Lemon, J. Brazil. : CW69-5/207E-PDF

"Concern for the status of Harlequin Ducks (Histrionicus histrionicus) and Peregrine Falcons (Falco peregrinus) resulted in cost-shared surveys of breeding distributions in coastal areas and watersheds of Labrador in late July-early August 1987, 1988, and 1989. Further to these surveys has been the original research associated with the Environmental assessment of low-level flying, field work associated with the development of avoidance criteria for low-level flying, and preliminary surveys of tributaries of the lower Churchill River presently being assessed for hydroelectrical development. In 1992, aerial surveys of waterfowl breeding in the upper Churchill River watershed were conducted under the Canada-Newfoundland Comprehensive Labrador Cooperation Agreement. Overall, avifaunal surveys of Labrador have been very limited. We recorded all faunal observations, and significantly increased data on distribution and density of various other waterfowl and raptors, especially Canada Geese (Branta canadensis) and Golden Eagle (Aquila chrysaetos)"--Introd., p. 2.
