A free winter walk to view eagles, owls, alcids, sea and bay ducks, buntings and longspurs along Long Island Sound will take place at 8 a.m. Saturday at Westport's birding hotspots, including Sherwood Island State Park.

The walk is sponsored by Sunrise Birding as part of a series of winter bird walks to search for the varied habitats of the Connecticut shoreline. Tina Green will lead the walk.

Space is limited and registration is required by visiting www.sunrisebirding.com. A confirmation with directions and meeting locations will be e-mailed to registered participants a few days before the walk.
