Bird Watching Resources:


On November 8, 2008 the ecosystem of the San Francisco Bay and surrounding Pacific Ocean took a jolt from a industrial marine accident that spilled a large quantity of oil into the water. This video was taken a week or so later and shows pelicans enjoying an early morning bath in the fresh water of the lagoon with the oil spill being cleaned by men in hasmat suits on Rodeo Beach, Golden Gate National Recreation Area, behind.


SEA BIRDS OF THE SAN FRANCISCO BAY AREA, ADJACENT COASTAL WATERS, AND GULF OF THE FARALLONES MARINE SANCTUARY.



Seabirds are birds that have adapted to life within the marine environment. While seabirds vary greatly in lifestyle, behaviour and physiology, they often exhibit striking convergent evolution, as the same environmental problems and feeding niches have resulted in similar adaptations. The first seabirds evolved in the Cretaceous period, and modern seabird families emerged in the Paleogene.

In general, seabirds live longer, breed later and have fewer young than other birds do, but they invest a great deal of time in their young. For example, "March of the Penguins" was a movie that made famous the devout parenting instincts of Penguins. Most species nest in colonies, which can vary in size from a few dozen birds to millions. Many species are famous for undertaking long annual migrations, crossing the equator or circumnavigating the Earth in some cases. They feed both at the ocean's surface and below it, and even feed on each other. Seabirds can be highly pelagic, coastal, or in some cases such as the albatross, spend a part of the year away from the sea entirely.

Seabirds and humans have a long history together: they have provided food to hunters, guided fishermen to fishing stocks and led sailors to land. Many species are currently threatened by human activities, and conservation efforts are under way.
