1977 Walter D. Koenig 4 Melanerpes formicivorus Lambert Hastings Reservation 27 May 1315. 2 or more birds in the vicinity, but no one in any holes. Later I climbed up into the Valley Oak granary on HNHR to discover the nest hole opened by Michael way back when (I hadn't even known this particular hole existed!) So I opened it, just to make sure, and found all the makings inside of a Woodrat nest, but nothing relating to woodpeckers. 31 May 1 June 2020. 22 birds roosting in one of the holes in the Valley Oak along the fence line up from the '75-'76 nest tree. 5 June 1515. Nobody in any of the holes here. 7 June 1145. Still nobody seen here in/out of a hole. √ 10 June 2000. Counted stores: 855, all in the Hastings fallen tree. So where the hell's their nest?? At dusk, I flushed 1 bird out of a hole in the upper Valley Oak along the fence; it may be the nest, as best I could tell a single bird insisted on returning there a couple minutes later to roost. I don't know where anyone else roosted, even though I checked the other areas. 11 June 1900. Saw nobody up here. Watching here is rapidly becoming a must. 12 June 1935. 9 in that same hole in the tree up along the fence from the main nest tree. Surely this is it (but I'll have to wait until at least tomorrow to open it and know for sure). 13 June 1100. Even though nobody was in the hole, I went up and opened it. It is a nice hole, but there's nothing in it yet. The mystery remains unsolved for now. 15 June 1915. As usual, I see no one in or near any holes here.
