MDAS Field Trip — Mt. View Sanitary and McNabney Marsh

March 14 @ 9:00 am - 1:00 pm


Mt. View Sanitary and McNabney Marsh
Tuesday March 14, 9 AM to 1pm

Starting at the Mt. View Sanitation District Administration Building, we will spend most of our outing walking around the several large ponds that make up Moorhen Marsh. Parking is free, and there are restrooms at the beginning of the walk. Winter birding at the Marsh has been excellent so far this year, and hopefully, March will be no exception. Some of the types of birds we should see include: swans, pelicans, ducks, egrets, herons, coots, grackle, gulls, and hawks. Following our walk around Moorhen, we will drive the short distance to the other side of I-680 to the birding platform at McNabney Marsh, look for ducks and waterbirds there. Depending on how much fun we’re having, we may extend the trip across the marsh at Waterbird Regional Preserve.

This trip is well-suited for beginners. If you’d like to borrow a pair of binoculars to use while on the trip contact leader Matt Tarlach, after you register.
