Meet at the Lakeville Park and Ride at the west side of Rte. 101 at Rte. 116 at 9:00am. We will carpool to Arrowhead Marsh in Oakland. A predicted 6.7 king tide at noon here should make conditions great for viewing rails. Soras might be seen swimming in channels and hopefully we will be able to see Ridgway’s Rails and if we are incredibly lucky – a black rail might show itself. It is also a good time to look for Nelson’s Sparrows. Of course, even if nothing unusual gets seen, it is always fun to explore a new place. Bring binoculars, field guide and/or app, lunch, water, snacks and of course layered clothing.
