Went out this morning to do some chipping of downed tree branches and stopped by the nest box - no eggs. I came back by a couple of hours later and found this. She must not have minded the chainsaw and wood chipper racket in the background.

By my calculations:
One egg per day for the next 4 days + 14 days incubation + 17 days for growth and "preparation", we should have fledging around May 16 or 17.
