24 May Evidently things have been messy here, as I just found
the nest here and it's fresh, with 3 eggs (it's in a new hole
in The Black Oak). As most of The holes here are easy to
get to, I should ambush here, and maybe even to DLWater.
3 June 1530. Checked the hole: 1 hatchling and 2 developed eggs.
Today is hatching day.
Clutch size: 3
Est FED: 22 May
12 June 1145. Nest is empty! It failed.
