1982 R.C. Mumme Melanerpes formicivorus Lower Haystack 25 Feb Last of the granary censuses here, 1100-1300. Again I heard ♀587 do some chatter to the adults. Also, the residents here were hassling a ♂ Kestrel that every so often flew into the granary. Complete census (♂461, ♀♀523, 524, 587) Once again, and this should be last watch here for awhile. 27 March Counted stores, 1500: 2° granary 105 1° granary 3870 2975 TOTAL 13 April Alan + Molly have reported activity here in the 1979 nest hole in the granary. I reopen it at 1100, but find that the hole has been substantially deepened, requiring a large new cut (that just barely allows me to reach the bottom). No eggs. 15 April Molly has reported little or no action in the 79 hole, so I watch briefly up here, 1400-1530: I see almost nothing: However, the birds were hanging around the Poison Oak - Blue Oak Nest Tree, and at one point I saw ♂461 look into that hole, and a ♀ enter for about 10 sec. I check the hole, + like last year, it is totally devoid of any wood chips. Hopefully, these birds aren't serious about nesting yet. 19 April A quick watch here, 1010-1110: Nothing much. Birds flycatcher like mad, primarily from the Blue Oak nest tree area, and from ♂461 FTF all the granary. No action in any holes, although ♀587 perched the ♂ at least in the 79 hole after Swallows were in the vicinity. As Molly had mentioned, a ♂NB seemed to be around the 2° area abit
