Wapack National Wildlife Refuge was New Hampshire's first refuge and was established through a donation in 1972. The 1,672-acre (677 ha) refuge is located about 20 miles (32 km) west of Nashua, New Hampshire and encompasses the 2,278-foot (694 m) North Pack Monadnock Mountain. The refuge is a popular hawk migration area and provides nesting habitat for numerous migratory songbirds such as the American tree sparrow, Swainson's thrush, magnolia warbler, crossbills, pine grosbeaks and white-throated sparrow.
