1992 Walter D Koening Melanerpes formicivorus 1800 HNHR (15 May) this rather precarious snag and opened the hole: 3 fresh eggs. From watching it I do think it's 1800's hole, not Hay-Blom's. 21 May 1650. Checked the hole again: 4 eggs. Thus, LED = 16 May; should hatch ~27 May. 19 June 1530. Banded and bled the 3 babies here. (One a runt.) 1 July 1530. Stores remaining in the granary here. 5 September 1715. Stores are exhausted here, or very nearly so. 7 September 1500. Watching hole from spring. 1515. Bird fed!! 1600. Climbing the hole, 1 baby jumped out; Alice, a prospective student who happened to be with me, got him. Hole was otherwise empty, so unless he's the last to go, it's a brood of 1 here. I took him back to the Lab to band & bleed and returned him at 1630. Holy cow!
