The Lehigh Gap Nature Center will host “A Buzztail Odyssey: The Pennsylvania Timber Rattlesnake Project” from 7 to 8 p.m. Thursday.

The in-person event features guest speaker Rob Bertoni, a deputy wildlife conservation officer with the Pennsylvania Game Commission and a field specialist with the Pennsylvania Fish and Boat Commission’s Timber Rattlesnake Site Assessment Program.

Bertoni will talk about the origins, evolution and discoveries of the Pennsylvania Timber Rattlesnake Project, a 20-year citizen science effort.

According to information from the Pennsylvania Department of Conservation and Natural Resources, the secretive reptiles are frequently misunderstood and feared, even though they are important links in the food chain. Timber rattlesnakes help to keep the small mammal population (and their pests, such as ticks) under control.

The program is free to nature center members. A donation of $5 will be collected from others.
