This morning a quieter seawatch with the highlight a smart, close Roseate Tern. From there it was to Washington WT for the mystery peep. Seen almost immediately on arrival it was clearly not a Little Stint and good scope views of it on hard ground revealed the diagnostic semi-palmations of a Semipalmated Sandpiper. The day improved further when a Spotted Crake appeared just inches from the Sandpiper. Unfortunately this dashed into the sedge, having been seen by just three of us.
