[Maine-birds] FOY barn swallows - Sebasticook River Rt 139 Farm Benton

The barn swallows are back in the middle of the range of 5 days they have arrived over the last 9 years.  They are checking out the old nesting sites in the barn, carriage house and shed.  The barn swallows and tree swallows are great summer guests.  I need to look for the orioles and king birds down at the river.  /Allan
