In conjunction with the exhibition, Passing By: Mixed Media Installation by Joan Webster-Vore, the Museum will present a talk by naturalist Joel Greenberg, author of  A Feathered River Across the Sky: The Passenger Pigeon’s Flight to Extinction, the first major work on the bird in over fifty years. Greenberg will examine how one of the most abundant birds in the world was driven to extinction over the course of a few decades due mostly to unbridled killing for food and recreation.
