Wildwood Zoo Providing Update on White-Tailed Deer Herd

Thursday, September 10th, 2026 -- 10:00 AM

Wildwood Zoo is providing an update on its white-tailed deer herd following the loss of several animals this summer. 

The zoo knows how much the community loves the pasture animals, and they appreciate everyone who stops by to admire them. Losing Grant, the zoo's longtime buck, earlier this year, followed by two does, has been difficult for staff and the community.

As the herd ages, some losses are a natural part of caring for these animals. However, the zoo wants the community to know that every deer that has passed away has been tested for Chronic Wasting Disease (CWD) and tuberculosis (TB).

The zoo is pleased to report that all animals tested negative or inconclusive, with the underlying cause of death consistent with old age. CWD is an always-fatal neurological disease that affects cervids, including white-tailed deer.

Because animals can carry CWD for an extended period without showing symptoms, Wildwood Zoo tests every cervid that passes away as part of their commitment to the health of the herd.

The zoo has also heard many questions about when they will add more deer and whether baby deer may be part of the future herd. At this time, they do not have a timeline for additional animals. Any future additions will be carefully considered with the health and welfare of the herd as a priority.

The zoo appreciates the community's patience and understanding. If you encounter a wild deer that appears sick, has an unnatural head tilt, shows little fear of humans, or otherwise appears unhealthy, please contact the Wisconsin DNR at 608-267-0866. 

Do not approach a sick wild animal.

Thank you to the community for their continued support of Wildwood Zoo, their animals and staff. They are grateful for the care and concern everyone continues to show the herd.

Feel free to contact us with questions and/or comments.
