Osgood (1901) and Wailes and Newcombe (1929) noted that Pilot Whales occurred regularly off the British Columbia coast. Some subsequent authors have accepted these early reports as authen- tic (Scheffer and Slipp 1948; Leatherwood and Dahlheim 1978; Home 1980), although Pike and MacAskie (1969) discounted them, believing them to be records of Killer Whales {Orcinus orca). Baird and Stacey (1993) recently reviewed and summarized the presence of Short-finned Pilot Whales in British Columbia waters (Figure 2), and noted that the infrequency of sighting records between 1954 and 1989 lend support to Pike and MacAskie's (1969) conclusions. However, as Shane (1985) noted, warm water El Nino events may disrupt the distribution of Short-finned Pilot Whales, and their presence in more northerly waters could increase during such periods (see Movements, below). In total, only 21 occurrences of Short-finned Pilot Whales have been reported from British Columbia waters to 1989, only one of which is a stranding record, that of a single individ- ual (Pike and MacAskie 1969; Spong et al. 1972; D. F. Hatler 1972 [The mammals of Pacific Rim National Park. Unpublished report. National and Historic Parks Branch, Western Region, Calgary, Alberta]; Baird and Stacey 1993). Baird and Stacey (1993) concluded that Short-finned Pilot Whales should be considered rare in British Columbia waters; they are represented by only a few records in most, but not all, years. They caution however, that little sighting effort is m
