Least Terns, Farm Island Causeway
Hughes County, SD
June 8, 2015

The terns are foraging in the marsh and in Hipple Lake. They are also carrying
food back to the island by the boat ramp, so there is probably a nest somewhere there.
 I saw three Least Terns at one point in time this morning.
A Least Bittern was calling in the marsh while I was photographing Least Terns.
