HAWK Mountain

Jean Cecil of the Rachel Carson Homestead will present a free spring lecture, “Rachel Carson: A Sense of Wonder,” 5 p.m. April 30, Visitor Center gallery, Hawk Mountain Sanctuary, Albany Township and East Brunswick Township, Berks and Schuylkill counties.

The talk and slideshow highlights Carson’s conservation accomplishments and includes a virtual tour of the National Historic Place in Springdale, Allegheny County, that was her childhood home.

Carson was a world-renowned marine biologist and environmentalist. She was one of the earliest scientists to begin research on the effects of pesticides on wildlife. Her work culminated in the 1962 publication of the book “Silent Spring,” in which she included data from Hawk Mountain Sanctuary that documented a decline in the number of juvenile bald eagles seen on migration.

“Silent Spring” is believed to have led to the creation of a presidential commission that resulted in the banning of the pesticide DDT.

Registration for the lecture is recommended: 610-756-6961.
