FUR SEALS INCREASE AT CALIFORNIA ROOKERY A new breeding colony of Northern fur seals on San Miguel Island off California has more than doubled since its discovery in July 1968 by scientists from the University of Cali- fornia and the Smithsonian Institution. When the colony was found, there was a maximum of 86 fur seals. The herd was ruled by alone "beachmasterj" as a lordly breeding bull is called. 1969 Breeding Season At the height of the breeding season in summer 1969, about 175 females were on the island. There were 4 adult bulls; 3 of them presided over harems. There were fewer pups in 1969: only 26 compared with 36 in 1968. Reasons for the decline are unknown and BCF scientists will continue their study of the new colony. Following their migratory habits, more than half the fur seals had left the island by early October 1969.. The Northern fur seal has a strong homing instinct. It usually returns to the rookery of its birth each year during the breeding season. Fur seals from other rookery islands were the main source of the increased population in 1969. Santa Barbara Spill Dr. Leslie L, Glasgow, Assistant Secretary of the Interior for Fish and Wildlife, Parks, and Marine Resources, said he was gratified to learn of the increased fur seal population. This was because of public concern for marine mammals expressed during the oil spill in Santa Barbara Channel in early 1969. In June 1969, Interior Department reported no evidence that deaths of seals or sea lions on San Miguel Island could be attributed to oil pollution. In addition to fur seals, the island is inhabited by elephant seals, sea lions, some Stellar sea lions, harbor seals, and an occa- sional visiting Southern fur seal. The Navy owns the island.
