1981 R.L. Munnat Melanerpes formicivorus Sobo 7 April A quick pass here 1500, ♀847 NB the only ae in the granary. That is all. Nobody in either hole. 27 April Start watching here 1515. ♂638 metal/DPink and ♀640 Doreen/Doreen Dorn/metal (didn't see arrowness) in the granary momentarily, That ♀ flew off, but ♂638 did not follow. She (plus another bird?) flew off toward the northwest. Later ♂638 looked off SE. 1530, ♀847 NB comes by quickly, also flies NW. These guys still have a well-stocked granary. 14 May I say hello to the granary holes at 1230, but nobody looks out. I also wander all around the Bianca-Black Oak ridge near the granary, but find no reasonable looking holes. 17 May A walk by at 1130. Nobody in the holes in the granary 21 May An incredible struggle, but I finally find the nest here today, tipped off by the birds flying to it. It's a N-facing hole in the main trunk of a Black Oak just N of the "flat", at 45 meters west of the Ball fence line. Easy climb 22 May Open up the hole here 1400. 3 well-feathered, eyes-open nestlings (maybe 20-22 days?). Will have to band these guys soon! 24 May 3 young boded 26 May Watching nest ♂84 1640 End 1810. All 4 birds, ♂635 CBlue/DPink (at nest only once), ♂639 Yellow/DBlue, ♀640 DGrn-Red(iv)/M, ad ♀NB here. ♂639 is definitely the stud ♂. He fed many times and removed all the fecal sacs. Could detect no difference in behavior of ♀♀, but I suspect ♀640 is the brood queen is super.
