1245. Opened the new hole they've been working
on The lower, large limb: empty but close.
3 April
1500. Bird in the new hole again still empty.
1215. Checked low old hole (#264): 4 eggs.
I peeped it so I'm not sure how old they are.

915. 2 babies, 2 eggs - 1 infertile, other might
still hatch, I guess. © 23.7 x 20.5 © 24.6 x 21.3.

11 May
1500. Based on a tip from Jen, who watched here today,
I checked the new hole (see 28 March) and found
4 fresh eggs (EHD 22 May). Measured 1: 24.6 x 20.2.
Note: this may be the 1st definitive case I've
had of a group starting a second nest before the 1st fledged.
Note that the 2 kids are an est. 26 days old today.
