10,000 to >1,000,000 individuals
Comments: About 18,800 occur in Canadian waters in summer; no population trend is evident (Strong 1988). Total population in the 1980s probably was somewhere between 25,000 and 50,000 (Evans 1992; see also IUCN 1991). Further information on populations is needed (IUCN 1991).
