Mountain beaver broke into zoo's otter exhibit

A mountain beaver broke into the Oregon Zoo’s river otter exhibit last Tuesday.

The mountain beaver is a rodent found only in the Pacific Northwest and parts of California. It is not closely related to Oregon's State Animal, the North American Beaver.

Zoo officials said the elusive mountain beaver, also know as a boomer, was discovered in the river otter moat.

While there, zoo workers don't believe it tried to attack the otters. The perpetrating beaver was caught and released back into the woods.
