Nevins Bird Sanctuary covers 125 acres of diverse habitats, including wetlands, meadows, forests, and ponds. More than 200 species of birds have been recorded here, such as great blue herons, bald eagles, woodpeckers, and warblers. The sanctuary offers educational programs, guided walks, and special events throughout the year. 

The Nevins Bird Sanctuary, once part of the Nevins Family Estate was part of the bequest to the City of Methuen, when the last heir of the Nevins family Harriet F. B. Nevins passed away. Harriet was a lifelong champion of animals and nature.

The Sanctuary is framed by the Spicket River and MA-213. The Methuen Rail Trail bisects the 18-acre sanctuary almost evenly, but the birds and wildlife also make the many many acres of adjoining conservation wetlands their home.
