Despite the fact that beavers are on the city's official seal, one hasn't been seen in the city for 200 years. That all changed this week after biologists disclosed that they had videotaped a beaver swimming in the Bronx River.

The beaver's lodge made of twigs and mud, on the riverbank had been spotted earlier.

Experts say city dwellers can expect to see more of them, as their habitat continues to shrink.

They've nicknamed the beaver "Jose" in honor of U.S. Rep. Jose Serrano's work to clean up the Bronx River. Beavers disappeared from the city due to trapping in the early 1800s.
