There’s detective work to be done in the forest at this time of year.

A half-chewed acorn, a pine cone that looks more like a corn cob, scratch marks in the leaf litter: Join Darryl and Jackie Speicher from 8 to 9:30 a.m. Nov. 10 to find out what these signs mean.

Young nature enthusiasts and their families will explore the trails of Nothstein Preserve, off Route 191, in Paradise Township and learn how to spot the stories in the forest.

Participants will investigate tracks and signs, listen for bird calls and songs, and study the trees, looking for remaining bird nests from the summer.

The winter snow leaves a good record of the birds and other wildlife that crossed the trail. Look in the snow — or mud — for footprints that may help visitors piece together the animal community that uses the preserve for feeding and playing.

With newly honed observation skills, participants will also find an increased appreciation of the winter forest.

This event is part of the Water Wiser Kids Series sponsored by Brodhead Watershed Association, funded by a Dr. Claus Jordan Endowment Grant from Lehigh Valley Health Network Pocono Foundation.

Dress for the weather and wear sturdy hiking shoes.

The program is free, but registration is required.
