STELLAR SEA LIONS: September

Autumn is often a time to prepare for the trials of winter. Nowhere is this more true than in Southeastern Alaska. Today we’ll visit with Alaska’s Stellar Sea Lions. I’m Jim Metzner, and this is the Pulse of the Planet.

Lewis: A couple of things are going on right now. Primarily it’s a time of recovery.”

John Lewis is a wildlife biologist with the National Marine Fishery Service in Alaska. John, what’s happening right now in the world of the Stellar Sea Lion?

Lewis: Females have given birth back in May or June — they’re recovering of course from giving birth and raising their newborn pup. Many of them are pregnant again. Many of the young animals who were essentially thrown out of the nest back sometime in the spring are out foraging on their own. The males that have been holding territories are recovering from some of the territorial battles that they have had in the past summer. Many of the juveniles who were excluded from rookeries are now coming back on, mixing in with the population they were held out from during the breeding season. I would classify this time of year as one of gathering their energy again so that they can go into the winter months.
Stellar sea lions hate to be alone, but as soon as they come together, you hear nothing but bickering. It’s a guttural groaning burping sound, and if you listen very closely you can hear different ages and different sexes. The males have got a much deeper, much more guttural sound to them. You will hear pups who will bleat to the mother for identificiation.

Unfortunately, the population of stellar sea lions is on the decline. In future programs, we’ll hear more from the biologists who are trying to save them.
