Brookfield Zoo found an interesting way to recycle some of the hundreds of Christmas trees used in its annual Holiday Magic display.

While most of the trees were sent to the wood chipper, others found their way into animal exhibits, where they were repurposed as enrichment for reindeer, polar bears, lions and more.

Some of the animals appeared disinterested but others reacted with glee.

There’s nothing cuddly about the response of the zoo’s bison, though. In fact, the Chicago Bears might want to recruit this one for their offensive line.

During January and February, general admission to Brookfield Zoo is free on Saturdays, Sundays, Tuesdays and Thursdays (parking fees still apply).
