John Ball Zoo


We are looking for individuals, groups or families interested in helping scientists study amphibians! Listen for the vocalization of frogs and toads at your local wetlands and record what species are present.

Not already an expert in local frog calls? Don't worry we have some resident herpetologists with tips and tricks to make it easy. We will teach you all you need to know at our volunteer training session.

During the FrogWatch Season we ask that volunteers commit to collecting data approximately once a week for about 10 mins, at least
30 minutes or more after sunset. The season is very weather dependent but usually goes from March - June.

Online volunteer training sessions are offered in February and March, with optional field trainings in the spring and early summer.

2021 sessions scheduled for Sunday, February 28th, 1-3pm and Saturday, March 27, 3-5pm. Training sessions held online are recorded and can be watched when it works for you or your group.
John Ball Zoo hosts an active FrogWatch USA chapter, a citizen science program of the Association of Zoos and Aquariums (AZA)
