River Legacy is home to lots of very well-known mammal species such as bobcat, raccoon, squirrel, and armadillo. But, did you know that the North American beaver (Castor canadensis) also lives here? Here are some cool facts about one of River Legacy’s most secretive mammals.

• Beavers are the second largest members of the rodents, after the South American capybara. They can weigh up to 71 pounds!
• Beavers have an extra thick layer of fat under their skin. This helps with insulation from very cold water.
• Beavers are incredible architects! They are able to construct their homes in rivers, streams, and/or lakes using twigs, mud, sticks, chewed-on trees, and other similar materials.
• Beavers can remain underwater for up to 15 minutes!
• Beavers can use their tail to slap it on the water to warn other beavers nearby of potential danger, such as predators.

Beavers are largely nocturnal. The best way to find them during the day is during the dawn hours. Walking the trails close to the Trinity River or Snyder Creek during this time could provide you with the wonderful experience of seeing a beaver! We’ve even spotted one in our pond recently at River Legacy Living Science Center!

Learn more about the beaver and other animal architects during our NEW Animal Architects Summer Class in July. Spaces are still available for the class which meets July 9-13 and July 16-20. Sign up online at www.riverlegacy.org or call 817.860.6752, ext. 102 to enroll today!
