1982 R.C. Munne 5 Melanerpes formicivorus Lower Haystack 22 April 0605, watching from blind. Details of watch on back When I arrived at 0605, I said hello and a non-♀523 ♀ (no chipped bill) looked out. That was the likely time ♀524 laid, as she was never in the hole again at a really suitable time. ♀523 laid at about 0650. Anyway, I saw both ♀♀ in rout of the hole at least twice before I check the nest 0815 and find 2 eggs, one rutt + one normal (see next record for details) Janet watched some time after I did, and saw both ♀♀ in the hole several times each, and nobody threw 0 eggs out. What I presume happened is that ♀524 (her first egg) laid the rutt early, and ♀523 the normal egg later, and that egg-removal is now over here. Lots of chasing + intruders while I was up here, perhaps involving ♀587. See Molly's notes, as she watched up here in the afternoon 23 April Two more eggs laid today, and things are definitely over here. I watched from above the granary and got ♀-guarding data, or the backs. Here at 0555, once again ♀524 is in the hole looking out as I arrive. She leaves 0607. Egg presumably laid prior to this time 0641 ♀523 enters nest, immediately looks out ♀523 Goes down 0653: She leaves 0703 lays 0840 No other birds had entered hole: I checked the nest and found two more fresh
