Jim Parks and Julie Anne Collier of Wingmasters will bring five birds of prey, also known as raptors, to the library Thursday, July 12, at 7 p.m. The program explains predation, the birds’ place at the top of the food web, and their different hunting adaptations. Because many birds of prey are declining in number, the presentation also features one or more of the endangered raptors that Wingmasters cares for and explains why these species face an uncertain future.
