I stopped by the Mason Dixon Farm this morning to see if any migrants remained.
   At the east pond:
Mallard  1
Semipalmated Plover  2
Lesser Yellowlegs  1
Semipalmated Sandpiper  24
White-rumped Sandpiper  1
Dickcissel  1 singing from the sprinkler line
Bobolink  1, at least, singing from the field to the east

   At the west pond:
Canada Goose  12
Mallard  1
Spotted Sandpiper  2, probably the local breeding pair

   At Shoemaker Road the Dickcissels were seen copulating, the female holding nesting material in its beak.
