1976 Walter D. Koenig Melanerpes formicivorus Bianca Hastings Reservation (7 May) 1400. Well, I went ahead and went up to the attended hole, (began to open it, and discovered the contents to be — that's right — no less than 4" of water! Examining the place, I haven't the foggiest how it got in there either. The slope is nearly vertical but no doubt 5° or so tilted down, facing about East, and no holes above it through which it could have dripped. Is it possible that the birds actually put the water there mouthful by mouthful as a reservoir? It is rather hard to imagine, but then again... 9 May 915. Watching. One bird flycatching in storage area when I arrived, flew to Valley Oak storage tree on knoll. 922. Ms Bianca and another bird hawking just over knoll. ?RRR#251 hawking over there also. 947. An intruder just displaced toward Arnold Field by 4 birds from the central storage area. 950. I'm going to move around to above the "nest" tree. 1015. ?Y?ped/Com#141 above me in perch Black Oak. ?R/W#42 also. 1100. I perhaps ought to come and try early in the morning, but there seems no activity focusing on any of the holes here now. I'm off. 10 May 1210. Watching from above storage tree. Nobody in holes over here; in fact, there doesn't seem to be anybody anywhere. 1217. 4 birds landed quietly and together in the storage tree, then flew to Blue Oaks at the ravine. (?141 among them). 1303. ?140, several others have returned. Birds are showing interest in a spot in the Black Oak: if there's a hole there, that's it. 1310. Going to check—
