2017 Wissahickon Birdathon

Friday, May 12 & Saturday, May 13

WVWA invites all birders to join the 23rd annual Wissahickon Birdathon! 

During this fun and friendly competition, teams of bird enthusiasts canvass the Wissahickon Watershed and strive to identify as many bird species as possible within a two-day time period.  Birders of all ages and skill levels are encouraged to join the fun! Bird as much or as little as you choose on Friday and Saturday, and enjoy the camaraderie of fellow birders and the beautiful birds passing through.  Teams use a checklist to record their sightings; following the event lists are complied both by species and by locations (see below, and use these lists to plan your team's itinerary).  The combined teams generally identify 120 -130 species!

Teams may collect pledges to support WVWA's efforts to preserve and restore habitat for birds and all wildlife.  Partner teams my pay a registration fee to WVWA and collect pledges for another conservation group.

Mid-Flight Pizza & Beer Party - Friday, May 12 - 5:00 p.m.
