1991 Walter D Koenig Melanerpes fomnicivorus Bianca HNHR 6 January 1990. Counted stores: "Main" tree: 150 Small to by nest area: 310 460 It's still a mystery why these birds store so few acorns in their "main" granary; it's fairly empty and could probably hold 1200 acorns if they worked at it. In all, I'd put capacity at about 1700 here. Obviously they aren't doing so well, although they do have some acorns. 27 January * Group update * 81517. Last seen 26 July, gone by 10 Oct → DA 2 Sept ±1 Mo. 2 April 1120. No stores seen here! 12 May 1840. Bird in the '89 nest hole. Nesty, perhaps? With 2♀, it might be worth watching here. 13 May 900. Checked the hole: looks not quite ready (but close); I doubt they've laid any eggs as yet. 8 June 1020. Watching for a bit. 1040. There are birds around, but mostly too far away to ID. 1048.♀ Lb/M #1462(?) ② ♀ Maawe/Yel #1463. 1105.♂ DB-or/Dr-DB #1232. 1110. Leaving. No sign of a nest, but the birds (minus, perhaps, the helper ♂) are definitely here. 15 June 1445. ♀ R-BLK/Red sapsucking. No one in any holes. ~w/ binocs. Maybe ♂1232? I think or. 1449.
