Don Edwards San Francisco Bay
National Wildlife Refuge
Don Edwards San Francisco Bay National
Wildlife Refuge is a haven for many different
California clapper rails can sometimes be
seen in the marshes. They are an endangered
species, meaning there are very few left.
Gray foxes use underground burrows or
dens found in rocks, trees, or bushes.
Green sturgeon and leopard sharks are
among the species caught by fishermen at
the Dumbarton pier.
These northern shovelers are a common
sight in the wintertime, when thousands of
ducks arrive at the refuge.
Rare salt marsh harvest mice feed on
pickleweed. They only live in the marshes
around San Francisco Bay.
American avocets can often be seen foraging
for food along the mudflats.
Barn swallows nest along the bridges and
buildings in the spring, darting through the
air to catch insects.
Western snowy plovers raise their young
along the sand and mud flats of the refuge.
Western fence lizards sit out on rocks and
paths, soaking up the sunshine.
In the summer, harbor seals sometimes
come up the sloughs to haul out and rest.
Together, we can make San Francisco Bay a
place for people and wildlife to share!
