Dig into the science of songbirds during this bird banding demonstration by ornithologist Dr. Jon Atwood (Massachusetts Audubon) and his longtime banding partner, Polly Pattison (Harris Center). You’ll learn how biologists use delicate mist nets and lightweight metal bands to monitor migratory bird populations, and enjoy up-close looks at some of the songbirds that nest in our neck of the woods. 9 to 11 a.m. at the Harris Center. Rain date: July 29. For more information, please contact Brett Amy Thelen at (603) 358-2065 or by email.
