The Fairfield Woods Branch Library will sponsor a hike Oct. 1 at the Connecticut Audubon Center on Burr Street.

Participants will meet 9:30 a.m. at the branch, 1147 Fairfield Woods Road, for information about the free hike using Pequot Press' "FalconGuides," which may be checked out of the library.

They will then drive to the head of the trail at the center, 2325 Burr St., to observe and identify animal scat and tracks. Hikers may bring binoculars, a compass, snacks and water.
