1991 Walter D Koening Melanerpes formicivorus Plague HNHR 4 January # 1015. Counted stores: Main tree: 2760 20 tree: 167 Misc: 97 Total 3014 This group is doing fine, but even here the granary isn't especially full. Also, they lost a limb last month of unknown size (to me), but apparently large enough to be of note (300 holes?) 3 March *Group Update* j1865. Only seen once after fledging by Nancy on 4 Oct; gone by ~24 October → D.A. 14 Oct. ± 1 wk. 81530, 81733. Last seen 8 December; gone by 14 Jan→ D.A. 25 Dec. ± 2 wks 13 April 900. Several birds fighting here; not a real power struggle but something is definitely going on. 90s. ? or /R-w(m) #1729 drumming (8 helper) over in the locust by Jim's Garage. 7 May 1400. Lots of chasing here (and there has been for the past hour at least). Also, I mended the "traditional" rest hole. 2? → 8973 ①♀ M/Red ? ②♂ M (only band) → ③♀ Reb/Wk-LB #973 ④ LG/DB (good look) is ♀ DB /M #973. 1430. There may be only 2 birds (8973 & 8♂LG/DB ) in the central area, always following each other. There are at least 2 other birds gamracking off in the periphery somewhere. 1450. Too hard to ID the peripheral birds. Leaving. The 2 birds, at least, look pretty tight. The♂ would appear to be 81757, a Chongo baby from 1989 not seen after banding!!!
