While looking for raptors along the Lehigh yesterday in Bethlehem a watched a group of tree swallows doing their thing up in the air over the river. It looked like they were heading in the downstream direction. Its not always easy to tell because they seem to fly every which way but straight.
I little later I noticed another group near the Bushkill in Palmer.
