Saw plenty of shorebirds along an actual shore this morning.  It is often true you see Killdeer in a parking lot, Curlew or Willet in a pasture, or even sagebrush, phalarope on the ocean, Black Oystercatchers on a sea stack…but today shorebirds were all ashore as I led a Golden Gate Audubon Filed Trip along the edge of the Albany (CA) mudflats.  There was an even dozen species present on just a few acres of mudflat at low tide.
