Present Range, Migration and Abundance of the Atlantic Murre in North America'
BIRD-BANDING JOURNAL OF ORNITHOLOGICAL INVESTIGATION VoL. XI JANUARY,1940 No. 1 PRESENT RANGE, MIGRATION AND ABUNDANCE OF THE ATLANTIC MURRE IN NORTH AMERICA' By R. A. JOHNSON' THE breeding range of the Altantic Murre (Uria aalqe aalqe) in North America is, 1 believe, very well known. In the following pages I have listed every breeding colony which I find to be in existence. Excepting the possibility that a few small stations may still be unreported from the eastern coast of Newfoundland and possibly one or more in Newfoundland Labrador, I believe the list is complete. Beginning at Bonaventure Island, Gasp• County, Quebec, one might outline the breeding range by traveling south- eastward to the Magdalen Islands, thence to northeastern Anticosti island, and the north shore of the Gulf of St. Lawrence east of Anticosti; then, proceeding eastward along the North Shore, one finds the greatest concentration of breeding coloniesin the region around Cape Whittle. Besides these, there is a small colony near Bradore, at the west end of the Straits of Belle Isle, two on the east coast of Newfoundland Labrador, two on the east coast of New- foundland, and the Funk Island group. PRESENT ABUNDANCE The total number of breeding birds of this speciesfor eastern North America, accordingto this study is approximately 60,626. The notes which follow the tables (list of individual colonies)explain the manner by which I have arrived at a count of the breeding population for each colony. In the region of the north shore of the Gulf of St. Lawrence there is a greater number of individual breed- ing colonies.
