No third egg was visible by the end of camera streaming from Nest 1 on Thursday. On Friday morning, Mrs YA was incubating. She stood up about 09.30 and it looked as though there might be a third egg; two Rangers agreed we couldn’t be sure.
But at just after 10.30 when she got up to shuffle them it was clear a third and paler egg was nestled with the first two. So it was laid between 17.00 on 1 May and this morning at 09.30.
Probably this is the full clutch.
On Nest 2, the Ranger saw Mrs 37 tight on her egg(s) yesterday in the rain. Egg-citing times!
