Feather Trails: A Journey of Discovery Among Endangered Birds

Speaker: Sophie Osborn (remote)

Birds are visible, vocal sentinels that alert us to environmental harms through their declining numbers or their failure to thrive. In her new book Feather Trails—A Journey of Discovery Among Endangered Birds, Sophie Osborn shares her personal experiences reintroducing endangered Peregrine Falcons, Hawaiian Crows, and California Condors to the wild. While immersing readers in the triumphs and tribulations of being a wildlife biologist, Sophie explores the threats that imperiled these birds—threats that are harmful to us, too. She will discuss what led to the endangerment of these three captivating species, recount the efforts of biologists to recover their populations, and read a few excerpts from her book that describe what it was like to work with these magnificent birds.

Sophie A. H. Osborn is an award-winning environmental writer and wildlife biologist whose work has included the study and conservation of more than a dozen bird species in the Americas. She contributed to reintroduction efforts for several endangered birds and served as the field manager for the California Condor Recovery Program in Arizona for four years. Her books include Condors in Canyon Country, which won the 2007 National Outdoor Book Award for Nature and the Environment. She has written articles for BirdWatching, Wyoming Wildlife, and Sojourns magazines. Sophie’s writings are also available on her website and her “Words for Birds” Substack.

Pennypack on the Delaware is uniquely positioned along the river providing crucial habitat for migrants and the odd rarity. The flats at the confluence of Pennypack Creek and the Delaware frequently host gulls and shorebirds. The park also hosts Philadelphia’s most viewable Bald Eagle nest. Dress for weather.

Let’s meet at the covered picnic area at the ballfields (GPS: 40.0277033, -75.012093).

No binoculars? No worries! Birding backpacks with binoculars and field guides are now back on loan at the following local Philly libraries: Andorra, Cobbs Creek, Cecil B. Morre, Falls of Schuylkill, Frankford, Greater Olney, Logan, Richmond, South Philly, Torresdale, and Widener.
