Felix Neck needs birders and sponsors to participate in Mass Audubon’s 27th year of birding competition. Birders and donors raise money for Felix Neck Wildlife Sanctuary and its programs by getting pledges per number of bird species seen or making a donation to the Felix Neck team.

The 24-hour competition starts at 6 p.m. on Friday, May 14, and runs through 6 p.m. on Saturday, May 15. But you don’t have to participate the entire time — rotating shifts among teammates is encouraged.
