Wisconsin DNR inviting community scientists to survey wildlife in August and September

Aug. 8, 2025

Wisconsinites can become community scientists by participating in Operation Deer Watch and the Game Bird Survey.

These surveys are designed to measure the reproductive status of deer and game birds by establishing ratios of adults to juveniles (e.g., fawn-to-doe ratios). This data helps indicate the productivity of Wisconsin’s deer and game bird populations. The data from these surveys, along with harvest information, provide DNR scientists with the key elements needed to make knowledgeable management decisions for these species.

Participation in Operation Deer Watch and the Game Bird Survey requires no registration, and observations can be recorded using a mobile device. If in a vehicle, participants should only record sightings when their vehicle is stopped and not while driving.

• Operation Deer Watch – Members of the public can report location, age, sex and the number of deer seen from dawn to dusk during the summer months. This information helps to determine the fawn-to-doe ratio and, ultimately, deer population estimates. The deadline to submit observations is Sept. 30.
• Game Bird Survey – Members of the public can collect information on the types and numbers of game bird broods they observe during the summer months. This information is the basis for monitoring the reproduction of game birds for that breeding year. The deadline to submit observations is Aug. 31.

Please do not use the app while operating a vehicle.

More information and downloads for both surveys are available on the DNR’s Operation Deer Watch and Game Bird Survey webpages.
