1991 1992 Walter D Koenig Melanerpes formicivorus 1800 4 January 1200. Counted stores: Main tree: 2475? 2475 2° tree: 0 Doing quite well here. Tree (main tree, anyway) is close to capacity. I'd guess overall capacity at about 3000. 10 April A good proportion of The Live Oak up the hill has disintegrated, taking last year's nest hole (and the other former holes in this tree) with it. Lots of stores left here, along with 2 of Moraes feeders. 940. ♀ R-C/M #787 flycatching in granary. A ♂ here also. 850. Set up to nab 9787 for DLW. 950. Got her. 19 June 1035. Back for the recapture. 1215. ♂♂ are feeding but no sign of The ♀! 1258. Finally! Got her! 15 July 1645. Lots of stores left here (a supplemented group). 31 December 1530. Counted stores: Main tree: 1505. 2° tree: 0. I can't be sure, but I suspect that many of the acorns still stored here are from last year (i.e., fall 1990). (Note that this group probably never ran out of acorns, having been supplemented all spring.) 1992 4 April 1800. There are a fair number of stores remaining here: perhaps on the order of 500+. 9 May 1800. No one in the hole in a snag way up the canyon 3/4 up Haystack that 4+ birds roosted in last night. No nest here, I guess. 15 May 1145. Birds going to and in the roost hole. Climbed up
