And I thought we had a calm Easter 

You know, jeanne, I was just thinking about that whole Easter thing. E aster was early this year.  Last year,  Good Friday was April 5 or 6.   That's when we lost Unity, and Beauty returned from rehab.  
And Mariah and Beauty's battle was on an Easter Sunday too.  I wonder what date that was?  
I wonder if hormones of these birds reach a sudden peak during that first week in April?  
Birds are so cyclical.  I could count on the date that certain birds would return to my yard every spring and just stay for a week or so and move on.  
I wonder if that is how it is with these falcons.  Scary day.
