Guided walks led by San Diego Audubon docents include possible sightings of Brant Geese, eight to ten species of ducks, Peregrine Falcon, Belding’s Savannah Sparrow, and perhaps 30 other species. Birders will have a choice of walks on flat terrain. One walk is a 2.5-mile out-and-back amble; the other is an approximately 5-mile loop that will go around the perimeter of the levees. Dress in layers. Rain cancels. Coordinator: Brian Moehl, 858-273-7800 x103.
