Wissahickon Trails invites all birders to join Wissahickon Birdathon 2021 Edition! 


Whether you look out the window, explore your yard or neighborhood, visit one of Wissahickon Trails’ preserves, or venture to a nearby park, set time aside for the enjoyment of birds and raising critical funding for Wissahickon Trails critical conservation work.   Teams explore the Wissahickon watershed to identify as many species as possible during this 24-hour fundraiser. Birders of all ages and skill levels are encouraged to join the fun!


Now in its 27th year, the Birdathon is a treasured spring ritual of our Wissahickon Trails community. In order to allow teams and individuals to practice physical distancing, we are expanding the geographic limits outside of the Wissahickon watershed, to include Montgomery, Philadelphia, and Bucks Counties. Team members are permitted to bird individually and each team will compile a consolidated checklist from all of their members’ sightings.
