The last reported beaver in the Santa Clara Valley area was in 1855.

There's a mother and two "yearlings" at the beaver lodge, which is close to the city's downtown, which can be viewed on a video provided by the Urban Wildlife Research Project. The video was made on April 7 and 8.
The mother is pregnant, environmentalists said.
