Fall in the Air?

Summer just started, didn't it?  Where are the "dog days" and the 90 plus temperatures?  After a refreshing rain yesterday I got up this morning to the gas fireplace running strongly.  As the sun came up there they were.  Mourning doves sitting in the tree all hunched up.  Now of all the birds, the doves probably have some of the smallest brains but they do know something.  That is when fall is coming.  They are done raising their squab and are now just soaking up the sun.

This behavior is indicative of preparation for migration back to the south.  If I could read their tiny minds they are cooing to each other "what are we going to do in Mexico in a couple of weeks?"  Fall may come early this year.
