Nighthawks are among the last migrants to arrive each spring and the earliest to depart each “fall,” with southbound migration peaking in late August. Join nighthawk enthusiasts Cliff Seifer and Brett Amy Thelen to search for the spectacle from a vantage point in the Ashuelot River Valley. If it’s an average night, we should get great looks at a handful of these acrobatic birds. If it’s better than average, we just might see hundreds of nighthawks feeding in giant flocks. Bring binoculars, and be prepared for biting insects. Beginning birders welcome!

6 to 7 p.m. in the rear parking lot of Stone Arch Village at 831 Court Street in Keene, near the raised garden beds. This site is wheelchair-accessible.
