A week and a half ago, we published that photo taken by Tom Foley while out on the Duwamish River. We thought it was a Steller sea lion; turns out it’s a California sea lion – and known to researchers. LG saw Tom’s photo here and sent the information to NOAA, which she says “got excited about it, and e-mails were quickly sent around between people at NOAA and the Alaska Fish and Game Department’s Steller Sea Lion program trying to identify the animal. Apparently Alaska Fish and Game has an extensive photo database specifically for identifying branded sea lions.” She then received e-mail from NOAA’s Sharon Melin, who told her it was OK for us to publish the e-mail, which follows:

Thank you for reporting the sighting of the California sea lion #8727. He was branded as a 4 month old pup in September 2006 at San Miguel Island, California. At the time, he weighed 23.0 kg and was large for his age. He has been seen regularly in Washington during the winters and at San Miguel Island during the summer breeding season but still is too young and small to be breeding.

San Miguel Island is the northern limit of the California sea lion breeding range and is the westernmost island in the Channel Islands chain off the coast of California. Each year, a population of about 100,000 California sea lions returns to the island to breed and pup. Pups are born in late May and June and are usually weaned in March or April of the following year. Each year we tag and brand 500 pups out of about 23,000 born and conduct long-term observation studies throughout the lives of tagged individuals.

The tagging program for seals and sea lions on San Miguel Island was initiated in 1975. We have had tag recoveries from as far south as Pta Colnette (Punta Colonet), Mexico and as far north as Southeast Alaska. The tagging program provides information for long-term studies on migration, movements, survival, reproductive success, and annual cycles of individual animals. Studies such as these help us to effectively monitor marine mammal populations.

Tag returns are an extremely important part of our studies and they provide valuable information required to understand the biology and status of marine mammal populations. Thank you for taking time to participate in our research effort.

Here’s a map showing San Miguel Island, which is off Santa Barbara, California – more than 1,000 miles away!
