Bryce Robinson

In this presentation, Bryce will outline the work of the Red-tailed Hawk Project, including many stories of surprising things the working group has learned in their investigation into the unknowns of this common species.

Bryce W. Robinson is postdoctoral researcher at the Cornell Lab of Ornithology, where his research focuses on the evolution of diversity in the Red-tailed Hawk. As part of this work, Bryce co-created and leads the Red-tailed Hawk Project, a working group that aims to fill knowledge gaps in our understanding of the life history and evolution of the species. Additionally, Bryce is an ornithological illustrator whose work has been featured in scientific papers, on journal covers, and in logos for organizations and events.

Will Krohn

Purple Martins are the largest species of swallow in North America and, in the east, they nest almost entirely in human-constructed nesting colonies. Southeastern PA is one of two strongholds for Purple Martins in the state, and some of the largest colonies in Pennsylvania are in Chester and Delaware Counties. Purple Martins are a model organism for studying the migration and movement of songbirds due to their large size, conspicuous nature, and proximity to humans. They’re also a strong indicator of overall ecosystem health. Will's research seeks to uncover the rates at which young Purple Martins return to and disperse from the natal colony after hatching. Understanding how far Purple Martins travel from the natal colony is especially important since humans must construct all nesting colonies for the species. Purple Martins have declined by approximately 38% since 1970, so quantifying the rates and distances at which martins disperse will be a key tool for the conservation and management of the species. The Pennsylvania Game Commission and potentially other agencies will be able to use the information he collects in determining where they can best construct new colonies to bolster populations and connectivity, helping steer the recovery of this beloved bird.

Will Krohn is an M.S. student in Wildlife Ecology at the University of Delaware, studying dispersal in Purple Martins for his thesis. Will received his B.A. from Colgate University in 2023, where he double-majored in Biology and Environmental Studies. Since graduating, Will has worked as a technician on numerous avian research and conservation projects around the country, and in 2025, Will started his Master's at UD. Will is originally from Bucks County, PA, and he is an avid PA birder. In his free time, Will also enjoys rock climbing, hiking, and anything else that gets him out in nature.

Coordinated by TBD 

Every year, we end our meetings and presentations on the first Monday in June with a showing of members' photos.  If you would like to contribute and show your photos, below is the process for getting the photos to TBD.  This is quite a bit of work for the coordinator, so please get your pictures to TBD as soon as you can.

1. Maximum 50 photos per participating member
(depending on the number of people that want to show pictures, TBD may need to make a selection and pair the numbers down a bit.  We think the absolute maximum number of photos should not exceed 300.  E.g. if 7 people send 50 photos each, TBD will take out 7 photos per submission to bring it down to 301).

2. The photos need to be in JPEG format.  Ideally each photo file should be 2Mb or less.  However, if you don't know how to compress your files, TBD with do so himself if it becomes too much for the Powerpoint presentation file

3. Each file name should include the name of the bird.  If you want to also show on the slides the location where the photos were taken, please include the name of the location also in the file name, or include a Word document with the cross reference of location to the file name.  TBD will then make sure that the location is shown on the slides.

4. The photos should preferably be sent to TBD via websites such as DROPBOX or WETRANSFER.  These services are free if you don't exceed 2 Gb for the 50 photos combined.

5.TBD's email address is TBD

6. Please make sure to get your photos to TBD by May 15th at the very latest.  Earlier submissions are encouraged.

7. If you want to give the photos to TBD on a memory stick or a CD, get in touch with him via phone (cell: TBD) or via email to discuss day, time and location to hand over the memory stick or the CD, You can also mail a memory stick or CD to his home address at TBD.

NOTE: This meeting will be held in person at the meeting house and via Zoom. Zoom signon will start at 7:15 to enable the meeting to begin at 7:30.
