ABSTRACT

Forty-nine stranded cetaceans were recorded on Sable Island between 1990 and 1996. Ten species were represented in the island's records including one humpback whale (Megaptera novaeangliae), five sperm whales (Physeter macrocephalus), two pygmy sperm whales (Kogia breviceps), one dwarf sperm whale (Kogia simus), one northern bottlenose whale (Hyperoodon ampullatus), six long-finned pilot whales (Globicephala melas), eight Atlantic white-sided dolphins (Lagenorhynchus acutus), three short-beaked common dolphins (Delphinus delphis), seventeen striped dolphins (Stenella coeruleoalba), two harbour porpoises (Phocoena phocoena), two unidentified rorqual whales and one unidentified dolphin. Recorded events occurred in all months but April and June. The majority of stranding events (18) were of single individuals. Four events involved two individuals, two events involved three individuals, with one event of five white-sided dolphins, and two events of six striped dolphins each. Strandings of single individuals occurred in all seasons and on both the north and south sides of the island, while group strandings occurred only from October through March and most often on the north side.
