Description:

California sea lions (Zalophus californianus) are seasonal migrants to the Pacific Northwest, generally arriving around August and departing by the following June. The majority of California sea lions in the Pacific Northwest are juvenile and adult males, while females and young generally stay in the breeding range in California and Mexico (Odell 1981). California sea lions typically congregate at upriver sites such as Bonneville Dam and Willamette Falls each spring, peaking in April and May (Wright et al. 2010, Wright et al. 2014, Stansell et al. 2013).
