Not a whole lot of change in birds after the coldfront.  No Willet or Upland Sandpipers were found by me, but did end the morning tour of RMBS and the Confluence Point SP (all St. Charles County) with 20 species of shorebirds. 

 

Almost all of the below list is from walking to the back of the "Pipeline Pool" unless otherwise indicated:  

 

Lots of waders still, including 36 Snowy's

Sharp-shinned Hawk  1

Northern Harrier 1
Peregrine Falcon  1 (Also had 1 at Heron Pond, RMBS)
