Woodbridge Wilderness Area (formerly Woodbridge Regional Park)
This park consists of lush riparian woodlands nestled along the south bank of the Mokelumne River in the town of Woodbridge. The canopy is comprised largely of cottonwoods and live oaks. Willows and buckeye are also widespread. The understory includes blackberry brambles and poison oak in many places. Stinging nettle is plentiful also.
Birding the site: The entry is lined with pyracantha bushes, so be sure to check for possible Hermit and Varied Thrushes and Fox, Lincoln's, White-crowned and Golden-crowned Sparrows in winter. At the end of these bushes, the park opens up into a fairly wild area. All trails from this point are hard packed dirt which may be muddy in wet weather or impassable during high water. From here, you will see two trail signs in front of you on the left. These trails meander through the woods and eventually meet at an old fence which is the actual park boundary. If you choose to explore this end of the park, give yourself a minimum of two hours, preferably more.
For a much shorter hike, less than an hour, take the unsigned trail that dives into the woods to your right just beyond the first sign pointing to the trail to the left. Or, if you continue straight ahead from the park entrance, you will end up at the river. Any of these choices can yield good birds, depending on the season.
Year-round residents typical of riparian woodlands that can usually be expected include Wood Duck, Common Merganser, Cooper's Hawk, Red-shouldered Hawk, Great Horned Owl, Acorn Woodpecker, Nuttall's Woodpecker, Downy Woodpecker, Belted Kingfisher, Bewick's Wren, Spotted Towhee, Lesser Goldfinch and American Goldfinch.
