1993 1994 Walter Koenig Melanerpes formicivorus Road 1 HNHR 1 February 1600. Counted stores: Sycamore: 2085 Valley Oak: 950 Dead, spindly, tall Oak across creek: 590 } 3625 (wear '92 west hold) Even this may be an underestimate: the trees are loaded here, especially the Sycamore, which is so full it's hard to count. Note also that the tall spindly tree across the creek is emerging as a substantial facility; I assume it belongs to Road 1 since it's right near their nest, but there's no independent confirmation of this as yet. Someday, at least, it certainly could (and will) support a separate group (like Bongo). February [illegible] 8 April Stores still remaining here - plenty of them. 1994 21 January 1020. Counted stores: Sycamore: 1580 Valley Oak: 675 spindly tree across creek: 1096 } 3351 This group also is purported to be starting at Finch, where there are 339 acorns, although my guess is that they have perhaps "budded" off to it instead. In any case, they are doing well, though not fabulously so. 1 March Mark pointed out to me that the Sycamore granary has fallen! (not entirely, but the storage holes are a total loss). We saved a few limbs and peeled off a big limb on its to side next to the tree, but basically, they have permanently lost ~2000+ holes! 14 April 1015. Watching from the side of PO Hill.
