But if small "pockets" of habitat between southern Vancouver Island and Alaska are regularly occupied by whales in this way, then it will be important to learn the nature of this occurrence. For instance, if it were found that certain classes of whales, such as first-year ani- mals or non-breeders of one or both sexes, often do not make the complete migration to the breed- ing grounds, then the very sophisticated data on population dynamics obtained by Rice and Wol- man (1971) could be badly biased. Having said this, we hasten to point out that we have no evidence that this is so; our data are sufficient only to suggest that further evidence may be required to demonstrate that it is not. Perhaps the eastern Pacific population, having recovered from severe overexploitation relatively recently (Rice and Wolman 1971), is only now in the process of recolonizing feeding areas used previously. Perhaps the paucity of sightings out- side migration periods has been due largely to an absence of observers. We received an uncon- firmed report of four gray whales feeding near Nootka Island, 65 miles north of Wickaninnish Bay, in August 1973, and Pike and MacAskie (1969) report that "several gray whales [were seen] in late August and early September'' along.
