Two events are planned at the state parks in Barnesville, Schuylkill County, both on Saturday.

Conservation volunteer and avid birder David Kruel will lead a bird walk at Locust Lake State Park beginning at 7:30 a.m. at the park parking lot. Kruel will offer helpful information about how to identify the local and migratory songbirds by sight, song, habitat and behavior. The walk is sponsored by the Schuylkill Conservancy. Those attending are encouraged to bring along binoculars. This is not a pet-friendly walk. Shine only.

Starting at 10:30 a.m., naturalist Robin Tracey will lead a hike on the Crow, Lake View and Spirit trails. The hike is 9 miles long and moderate in difficulty. The hike combines the best of the trails in Tuscarora State Park. Participants will meet in the Crow Trail parking lot off Tuscarora Mountain Road. Call Tracey at 570-467-2506 between 8 a.m. and 4 p.m. for more information or weather conditions. This is a dog-friendly hike, but all pets must be leashed and get along with other pets and people. Shine only. Bring a lunch.
