1989 1990 Walter D Koenig Melanerpes fomiceivorus Bianca HNHR 4 May 1445. Set up, trying to catch ♂1232 at the nest. 1715. Got him. 2 August 920. I would be surprised if the granary here, which is empty at the moment, held more than 2000 acorns at full capacity. Certainly no more than 2500. 1990 10 January 1400. Counted stores: "Main" granary: 610 Small VO near nest tree: [illegible] The "Main" granary has acorns but still seems underutilized to me- I'd guess it's only 60% or so full. Otherwise, they have really begun to go on some new limbs over in the main area, particularly in the small VO root tree up and in between the old VO & Blk Oak granaries (both defunct for some time). All in all, I'd put capacity at ~2000 (not including the area 'z way up toward LA2, which no one's used for sometime now and is currently empty, as usual). 2 April 1110. The "main" granary looks pretty empty, but there are still some stores in the small VO near the nest tree. 13 April 1515. Watching. 1530. Birds around, but not in the main area. 15 April 1630. ♀ in last year's nest hole. 1800. Checked the hole: nice shape and ready to go, but empty. 2 June 1520. No stores remaining, lending some degree of reasonableness to that continued failure to find a nest here. 23 June 1550. Several birds in the upper trees up toward LA2; one being chased. Saw ♂ R/M #1515 and ♂ W/R-Or(N) #1517.
