DETROIT (AP) — Visitors to the Detroit Zoo in Royal Oak will get the chance to participate in data collection and other activities as part of Citizen Science Day.

Activities taking place from 11 a.m. to 3 p.m. Saturday include FrogWatch, which teaches volunteers how to identify frogs and toads by their breeding calls, and an e-bird activity that identifies native birds using silhouettes.
