This wetland complex along the Petaluma River is a wonderful setting for viewing a surprising array of birdlife, almost any season. In the fall and winter it hosts cormorants, herons, egrets, geese and swans, some raptors, many species of ducks and shorebirds — not to mention a great variety of songbirds (such as sparrows, finches, pipits, bluebirds). Terrain is flat, with a short walk of about 1-2 miles.
