Spotted Sandpiper and Least Sandpipers at Farm Pond

I took my lunch break at Farm Pond in Framingham, Massachusetts today.  Farm Pond is an urban setting, with a railroad switching yard , a city park, a yard waste dump, and commercial properties along the pond.

I was under the false impression (before this year and this blog) that sandpipers were found on ocean beaches and sandy lake shores.  Now I know differently.  I have seen them in Mt. Auburn Cemetery in Cambridge walking in the grass next to a pretty small pond and now here at Farm Pond, walking in the mud among the water lilies.
