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 expert birder Phil Brown and nighthawk enthusiast Brett Amy Thelen to search for the spectacle from a vantage point at the confluence of Nubanusit Brook and the Contoocook River in downtown Peterborough. If it’s an average night, we may 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. on the Brenner Bridge near Depot Park in Peterborough. Afterwards, all are welcome to reconvene for a pint on the patio of nearby Post and Beam Brewing.

Accessibility info: The Brenner Bridge is wheelchair-accessible, and there are two parking spaces reserved for people with disabilities in the adjacent Riverwalk parking lot.

This event is now full. To be added to the waiting list, please email Brett Amy Thelen or call Miles Stahmann at (603) 525-3394.
