The Chicago Zoological Society's ongoing commitment to conservation and education has led to groundbreaking advances in animal care, exhibit experiences, scientific discovery, and conservation education. The Annual Fund—unrestricted operating support from people like you—has made our successes possible. To show your support, make an Annual Fund gift by credit card online.

Did you know…
Your annual gift provides much of the funding to keep the zoo running. Annual Fund dollars keep the lights on at night, and keep the animals warm in the winter and cool in the summer.

In 2002, our revolutionary Hamill Family Play Zoo received the prestigious Exhibit Award from the American Zoo and Aquarium Association.

Our Sarasota Dolphin Research Program leads the world’s longest-running study of wild dolphins.

The Chicago Zoological Society is pioneering Conservation Psychology—a new field that examines why people care about nature, and what motivates them to conserve and protect it.

Without the Annual Fund, these and many other advances could not happen. Please consider a generous gift to Brookfield Zoo. Join us as we continue to lead the way in conservation and education.

To show your support, make an Annual Fund gift by credit card online.

Gifts to the Annual Fund are fully tax-deductible. No goods or services are provided in consideration of your gift. Don’t forget your employer’s matching gift program—make your support go even further!
