1991 1992 Walter D Koenig Melanerpes formicivorus Hay-Blom HNHR 5 January 1640. Counted stores: 3270. Doing just dantly here; est. capacity 3500. 3 March *Group Update* 61762. Last seen 14 June 1990, gone by 3 October, → D.A. 8 Aug ±2m. 61084. Last seen 27 Nov; either gone or lying very low since then. (28 Jan def. gone) → D.A. 27 Dec. ±1 mo. 15 May Watched here for an hour or so this morning, getting few cues as to a nest, although they do seem to be heading down into the forest relatively frequently. I did see a bird (and on Morni's feeder in the granary and take a piece of dog food. 850. Fm(Blk-Yel) #1648 from Blomone intruding here. 855. ♀ Yel-Red (Red) #1078 in granary. 945. Found a new hole in the forest near the old one; watched it for 20 min but no one came by. Still looks like a good possibility to me. 31 December 1630. Counted stores: 3100. These guys are essentially doing as well as last year! Again, is this partially because they were supplemented? Maybe they never ran out of stores? (Maybe Morni noted this.) Looking again, The majority of acorns stores are almost certainly new (this year's). There may be some old ones, but it's rather hard to tell. 1992 4 April 1810. A good number of stores still here, probably on the order of 1000 or maybe a few more. 3 June 845. Watching. There are still plenty of stores left here.
