2000 Walter Koenig 2001 Melanerpes formicivorus Lower Haystack HNHE 19 April) 1415. Lots of stores. None in a hole, but I checked the traditional hole anyway and was rewarded with 2 (cold) eggs: ① 23.8 × 19.6, ② 24.3 × 20.1. Need to check again for clutch size; EHD ~ 3 May. 23 April) 1645. 5 eggs. 3 May 1430. Hatching. 4 hatchlings + 1 egg, pipping and alive. No doubt all 5 will hatch, even if this last one doesn't wake it. Band: 24 May. 24 May 1400. Banded + bled the 5 babies. Plenty of stores. 12 June 1400. At least one kid plus an adult (inside excavating in the nest hole, but best I can tell it's empty. (But it's been deepened and I couldn't quite reach the bottom, so I couldn't be sure.) 19 July Still plenty of stores. 1530. They also have a nest! 4 kids (one smallish); a good 14 do (ELED ~ 25 June). Could be banded anytime, although I wouldn't go much past 26 July 21 July 1500. Banded The 4 kids (one probably won't make it; other 3 fine) in this 2nd nest. 30 August 930. Still stores. More interestingly, a decent power struggle is going on! Wonder what's up & who bit the dust? 2001 30 March None in the traditional hole, but I checked it anyway: empty. 9 April 1300. Bird in traditional hole, but still empty!
