General Discussion : First kestrels today!

I put up a kestrel box in March 2017 but had no visitors all last year.  The box is in the least used quadrant next to the house on the SE side overlooking the 17th hole of a golf course.  I was discouraged; but today I saw a male kestrel perched on the bird feeder in the back yard and have observed kestrels entering and leaving the nest box throughout the day. So March 5, 2017 is a day we will remember.
