Winter’s bare branches invite bird watching. So birders Henry Bornstein and Lisa Wilson are leading a free hike at Anderson Marsh State Park in Lower Lake with the hopes of catching sight of the park’s many feathered residents: great blue herons and great egrets as well as white pelicans, hawks, diving ducks, and grebes. The guided walk will be held on February 8 at 8:15 a.m. The trail route and length will be dependent on trail conditions, but will last about an hour and a half to two hours. Bring binoculars. Following the hike will be a tour of the park’s historic ranch house. If it’s raining, the walk will be canceled and the house tour will begin at 8:30 a.m.
