Mariton: Tree Swallows

June 30, 2011

Activity in the nest boxes is winding down.  These three tree swallows should be gone in two weeks. Last year, we had bluebirds nest very late in the season.  In fact, they started their nest July 19.  Normally, I stop monitoring boxes by that time of year.  It was pure luck that I decided to check one more time, and found the nest.  Four bluebirds ended up fledging out of that nest.  So, this year I will continue monitoring until the end of July, just in case.
