Meet the Island!

As the Northern Elephant seal breeding season is winding down, and coming to an end the Winter season crew enters a mode of reflection, of seals, life, and the island.

A Warming Ocean Brings the Tropics to the Farallones–But It’s Not Fun in the Sun for Everyone

The month of October had something of a tropical feel at Southeast Farallon Island–no, its barren rocks and few Monterey Cypress were not suddenly replaced by white sand beaches and palm trees, but recently, wildlife more characteristic of tropical latitudes have been visiting the island.

Conservation Conundrum: The interaction of Burrowing Owls, Ashy Storm-Petrels, and House Mice

This is understandable given that albinism is a recessive genetic condition that causes afflicted vertebrates to appear entirely white or pink, while animals with patches of white are often called partial albinos. However, by breaking down the three more common […]
