The Lycoming Audubon Society will sponsor the program, “Urban Crow Roosts” from 6-7:30 p.m. Monday, Sept. 10 at the James V. Brown Library, 19 E. Fourth St.

Dr. Margaret Brittingham will speak about the ecology and management of urban crow roosts. During the winter, American crows (Corvus brachyrhynchos) and to a lesser extent fish crows (Corvus ossifragus) form large roosts in urban areas where they can cause numerous nuisance and damage conflicts. Understanding roosting behavior and preferred characteristics of roost sites is essential for developing a successful management strategy that reduces conflicts in an ecologically sound and sustainable manner.

In this presentation, Brittingham will discuss research that she and her students conducted in Lancaster, quantifying local and large-scale movements of crows, timing and buildup of roosts, and response of roosting crows to harassment. She also will discuss strategies used by other communities to minimize crow human conflicts. For additional information on reducing conflicts with urban crow roosts see

Brittingham is a Professor of Wildlife Resources in the Department of Ecosystem Science and Management at Penn State University where she teaches ornithology and is a Wildlife Extension Specialist for Pennsylvania. Her research interests focus on avian ecology, human impacts on bird populations, the effects of shale gas development on forest birds, and the ecology and behavior of winter roosting crows. She is a member of the Pennsylvania Society for Ornithology, The State College Bird Club and The Wildlife Society. As an extension wildlife specialist for the state, she assists individuals and communities in developing strategies to reduce conflicts between people and wildlife.

A representative of the City will speak after Dr. Brittingham about their plan to address problem communal crow roosts in Williamsport this coming winter.

This program supports the PA Forward state initiative by providing social and civic literacy opportunities for learning and highlighting the transformative nature of public libraries within a community. Libraries contribute to education, employment, entrepreneurship, engagement and empowerment but are often overlooked as catalysts for powerful individual and community change. 

The program will be presented in the Lowry Room on the third floor of the Welch Children’s Wing. Registration is suggested, but not required. Visit to register or call 570-326-0536.

The James V. Brown Library is open from 9 a.m. to 8 p.m. Monday through Friday; noon to 5 p.m. Saturday and Sunday; and 24/7 at
