A few introductions to the team currently on SEFI are in order:
- Ryan Berger, Winter Biologist
This is Ryan's first season as the Farallon Winter Biologist. He has a background in animal behavior with a focus on marine mammals. Before joining PRBO, he worked with manatees for the Florida Fish and Wildlife Conservation Commission. He enjoys a healthy challenge, and attempts to tag and identify Rusty have not proven disappointing.

-Colleen Siudzinski, Winter Intern
Colleen has been working with wildlife in the Northwestern Hawaiian Islands for the past three years. She has extensive experience working with the endangered Hawaiian monk seal. She is quite comfortable with being marooned on a small remote island, but is looking forward to an adventure in a new environment.
|Colleen and MC Hammer
Jane studied developmental biology as a graduate student and is currently a postdoc working with microbial communities. She has been working with pinnipeds at The Marine Mammal Center during the past year. She has finally broken out of the lab for a unique field experience and is enjoying this introduction to macro-ecology.

-Sara Chandler, Owl Biologist
Sara is a graduate student at San Jose State University who is studying the winter ecology of burrowing owls. She has long been a fan of the burrowing owl, and other raptors and songbirds too. Sara has a background in wildlife biology, environmental consulting, and vegetation monitoring. She feels very lucky to be on the island
studying one of her favorite birds.

The elephant seal season is underway, and the bulls are starting to show up and stake out some territory. We have identified several bulls that were here last year, including the cantankerous favorite and one of last year's alphas, Rusty, as well as others such as Bedlam Boy and MC Hammer. These bulls will soon be battling for the prime territories to gain access to their harem of females. We've been working on identifying the bulls by reading their flipper tags as well as looking out for the arrival of pregnant cows, which should start happening in the next few weeks. Once the cows settle in, they will be giving birth to pups and nursing them continuously for about 3 weeks without leaving their pup, even to feed. After the pup gains a tremendous amount of weight and is weaned, the alpha males will mate with all of the females in their territory.
a brand new stamp. We've been having some problems getting the "Born Blonde" hair dye to show up well on the brunette seals that we have already stamped, so we are going to try out a different dye setup which will hopefully make the numbers stand out so that we can identify the main role-players quickly from a distance.

In between the elephant seal monitoring, our week has been consumed by extensive training for all aspects of our work on the island this season. We've practiced the routine for both the East and North boat landings, learned how to record weather conditions throughout the day, studied the names for different locations on the
island, and have been slowly becoming acquainted with the abundant bird life of the Farallones. We’re getting up to speed in terms of entering the abundant demographic data into the PRBO databases. We've also cleaned out the house and organized all of our food, fuel, and other supplies – out with the old, in with the new, for a new season.
Once we are fully settled and trained, a regular day for the elephant seal crew would go like this: a Western gull count at dawn, followed by breakfast and elephant seal monitoring. Twice a week we count all of the elephant seals present at accessible locations on the island. Once a week all of the pinnipeds are counted from the lighthouse. Twice a month, the California arboreal salamander population on SEFI is thoroughly monitored. After lunch, we go up to the elephant seal blind which hovers on a rock above Sand Flat and read elephant seal tags and note the new cow and bull arrivals. The day wraps up with a dusk gull count, data entry, and a consistently delicious dinner. After dinner, we record our findings for the day in the Farallon journal, which will eventually be bound and retained for permanent record. The workday of the burrowing owl biologist is quite different from that of the elephant seal crew, and deserves a blog post all of its own.
