1976 Walter D. Koenig Melanerpes formicivorus Ms. Bianca Hastings Reservation (13 May) About 8+ birds came to roost all, as far as I could tell, in the same two holes in the main storage tree where I caught them in December (the '75 nest hole and the one above it). Ms. Bianca was there. All in all it didn't provide much of a cue as to the nest, however. 14 May 1130. Watching. One bird flushed from the old upper nest hole opened by MacRoberts in the main storage tree; perhaps this is where things are going to finally get going. 1152. ♂ now peering out of the hole. I guess that's it for cure. 1200. leaving. Returning shortly, I opened the new nest and discovered 4 eggs! 15 May 1700. Checked nest: 5 eggs. 16 May 1500. 6 eggs! Ms. Bianca in nest when I arrived. 1600. ⚫ Nest checked: 6 eggs still, same as 16 May. #5 possibly not developing, or else just a little slow (slightly translucent still). 23 May 1730. Bird inside incubating. 26 May ⚫ 2000. Saw Ms. Bianca and several others in the territory; nestlings heard in nest - hatching has begun, at least. (It seems rather early, however!) 27 May 1920. While walking by the upper edge of the territory going through the forest to Black Dale, a bird who was secretively up in the trees here captured my eye. She was ♂ or/♂? who I would guess to be ♀14l of Bianca but then after watching her awhile a ♂ suddenly burst in from Bianca, apparently, and chased her like an intruder.
