Beaver Behavior and Ecology

The video explores how beavers fell trees and use wind to assist in the process. They manage branches and transport them through purpose-built canals. Autumn is a busy time for beavers as they prepare for winter by repairing dams. Moose benefit from the beaver ponds, which are rich in sodium. As winter approaches, beavers store branches underwater for food. Moose often interact with the beaver's food storage, but autumn is not a time for sharing.

How do beavers manage to fell large trees?

• They chew through the entire trunk.

• They make the tree unstable and let the wind do the rest.

• They push the tree over with their bodies.

• They use tools to cut the tree.

What is the primary purpose of the canals built by beavers?

• To create a habitat for fish.

• To prevent flooding in the forest.

• To transport branches to the dam.

• To provide a water source for drinking.

Why is autumn a particularly busy time for beavers?

• They focus on raising their young.

• They migrate to warmer areas.

• They prepare their homes for the winter freeze.

• They hibernate during this season.

What triggers beavers to repair their dams?

• The sight of predators.

• The sound of running water.

• The change in temperature.

• The presence of other animals.

How do moose benefit from the beaver's pond?

• They use it as a place to hide from predators.

• They drink the water for hydration.

• They feed on sodium-rich weeds.

• They use it as a breeding ground.

What do beavers do with smaller branches as winter approaches?

• They store them underwater for food.

• They use them to attract mates.

• They discard them as waste.

• They use them to build new dams.

How do beavers access their food supply during winter?

• They dig through the ice.

• They forage in the forest.

• They swim under the ice.

• They wait for the ice to melt.

Why might moose be interested in the beaver's work?

• To scare away predators.

• To help build the dam.

• To eat the twigs and branches.

• To find a place to sleep.

What is a challenge beavers face when moose come too close?

• Moose block their canals.

• Moose scare away other wildlife.

• Moose eat their stored food.

• Moose destroy their dams.

Why is autumn not a time for sharing for beavers?

• They are building new homes.

• They are raising their young.

• They are busy migrating.

• They are focused on storing resources for winter.
