Beware of falling bears.

The Independent reports:

Tranquilized bear falls out of a tree on Colorado university campus, becomes second bear to do this in three years

A university in Colorado was forced to call authorities on Friday when a two year old bear was spotted high up in a tree.

The authorities waited four hours for the bear to come down from the tree on the University of Colorado Boulder campus before deciding to tranquilize the animal, The Denver Channel reported.

After being tranquilized by the Colorado Parks and Wildlife department, the bear was captured falling out of the tree by a collage photographer.

The department then loaded the bear into a trailer and relocated it to the mountains.

This was not the first bear to have fallen out of a tree on a Colorado university campus, however.
