Friday, January 9, 2026 (Zoom only, the invitation link will be sent to members a few days before the meeting.)

“Why Tree Swallows Feather their Nests,” Lauri Green, Ph.D., Associate Professor of Biology, Commonwealth University of Pennsylvania – Bloomsburg. Dr. Green will examine why Tree Swallows line their nests with the feathers of other birds, what feathers they use, and the relationship of this habit to reproductive success.

“Do Female Birds Sing? “ - Dr. Lauryn Benedict, University of Northern Colorado

They certainly do! Female bird song is more common and widespread than is generally appreciated. This presentation offers an overview of the diversity of female songs, including a few used in spectacular partner duets. Backyard birders are encouraged to advance a growing body of knowledge by listening to singing females.

Dec. 2023 - Zoom Meeting 

Dr. Robert Curry, Villanova University - Dr. Curry is returning to present new findings in the Black-capped and Carolina Chickadee contact zone where the species hybridize. This long-running study now focuses on rapid northward movement of the hybrids. Collaborative work with the Lovette Lab at Cornell has identified a strong signal linking the hybrid-zone movement with climate change. New information from graduate student research focuses on changes in the Nolde Forest population. 

7:30 PM at Location: Nolde Forest EEC, 

(In person only, no Zoom*)

To paraphrase Thoreau, I have traveled much in Reading. A layoff and COVID-19 isolation allowed me to explore the bird life possibilities within the city limits. We'll talk about the places, the people and the birds I encountered during my City of Reading Big Year counts.

Mar 11, 2022 7:30pm - American Kestrel Conservation: Successful Partnership, PGC and the Birding Community  - Dan Mummert, PGC, Wildlife Diversity Biologist In 2015, the American Kestrel was added to Pennsylvania’s list of species of conservation concern due to a loss of nearly half their population since the mid-1960’s throughout North America. In response, the PA Game Commission’s southeast region created a kestrel conservation initiative that is working to learn more about their local population and help in their conservation. This presentation will discuss this program and the team effort it has been between the PGC and the birding community.  

Feb 11, 2022 7:30 pm - Ecology of the Northern Clapper Rail - meeting by Zoom only

Elisa Elizondo, University of Delaware, Ph.D. candidate

It's spring! Time to head for the coastal marshes with hopes of glimpsing elusive clapper rails (Rallus crepitans crepitans). The Saltmarsh Habitat Avian Research Program (tidalmarshbirds.org) is 

dedicated to the study of salt marsh birds and recent efforts led by Lisa Elizondo seek to uncover more information regarding this secretive species. This program will include recent data from Delaware on clapper rail nesting ecology and movement patterns, including the first chick survival data and the first GPS tag data.

(Meeting Via Zoom Only)
