Coast Trip: Parker River National Wildlife Refuge, Newburyport, MA
Saturday, August 22, 2026, 8 AM
Jane Wing, jeswing29@yahoo.com
Meet: Parker River National Wildlife Refuge Visitor Center, Newburyport, MA (GPS directions)
Please join us as we explore Parker River National Wildlife Refuge on a quarterly basis. While the focus for bird species will change quarterly, we will always have some overlap. During the winter months we will be looking for waterfowl such as loons, scoters, pintails, shovelers and more (maybe a Snowy Owl or two also). Spring, summer and fall, we will be looking for shorebirds, warblers, and potentially seabirds. Raptors may be observed every season. We may even encounter some rarities throughout the year! We will meet at the PRNWR Visitor Center and then carpool along the refuge. Most of the travel will be by vehicle, but we will also do some walking on the beach. We will have scopes available for others to look through, however, feel free to bring your own, if you have one. There is a $5 fee per vehicle to enter the refuge. Restrooms are available at several stops. If interested in carpooling, please enter your information into the carpool sheet. Be sure to check the meetup time for each trip, as the start time varies slightly by season.
Nature for All: Birding the Nighthawk Migration

Nate Marchessault, nate@harriscenter.org
Meet: Stone Arch Village rear parking lot, Keene (GPS directions)
Nighthawks are among the last migratory birds 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 great vantage point in the Ashuelot River Valley. If it’s an average night, we should get good looks at a handful of these acrobatic flyers. If it’s better than average, we just might see hundreds of nighthawks foraging in giant flocks. Bring binoculars (or borrow some from us), and come prepared for biting insects. Registration required, registration and more information can be found here.
