Spotted a lone TREE SWALLOW today and 5 SCAUP yesterday at the effluent channel here at work along the Mississippi River in St. Paul. I was unable to determine if the SCAUP were Greaters or Lessers as I had no binocs and was not all that close.
Seems early for the TREE SWALLOW, but can't say for sure without checking the expected arrival times. Mike Elling Ramsey County At work along the Mississippi River, St. Paul, MN Metro Sewage Treatment Plant Lab (Pigseye)
