Your support makes a difference!

Gifts of ANY amount to our Annual Fund are a critical source of funding used to support Brookfield Zoo’s areas of greatest need.

Your gift enables us to:

·  Continue to provide an outstanding level of animal care and welfare for the nearly 3,500 animals who call Brookfield Zoo home

·  Invest in habitat enhancements and enrichment devices that provide each animal the opportunity to engage with their surroundings as they would in the wild

·  Collaborate in field research efforts around the world, through initiatives like our Sarasota Dolphin Research Program

·  …and much more

Working together, we can ensure that future generations have the opportunity to enjoy wild animals and wild places. Thank you for investing in us.
