Every winter season since 1926, volunteers have spent a full day identifying and counting birds within a 15-mile diameter circle in Portland. Here at Tryon we generally spend a half day walking the trails and counting all we hear and see. Join the longest running citizen science project in North America! It’s also a great way to hone your birding skills. Ages 13 and up. Sign up online here. The group will meet in the equestrian parking lot.
