1976 Walter D. Koenig Melanerpes formicivorus Chongo Hastings Reservation 27 January 1530. 2 birds (nowing-streamers) flushed from the storage tree when I arrived. Checked marked acorns, finding only 23/60, with 5 moved. There are a few Q.agrifolia acorns stored here, in case I missed them with my sample. Count: 944 (this is very hard to count, of course, but there are still a lot here). 1615. Surprise. 5 birds, all tame enough to come land in the storage tree while I was standing below it, did so and began working stores together, as if they belonged here; the catch is that none of the 5 were banded. They included 4♂ and 1♀. After 6-7 minutes they flew over to the sycamore roost area, again as if they belonged here. At no time did anyone protest. At this point I will not even bother to stab at what's going on. 3 February 945. Watching sans hide. A bird garricked over past the sycamore roost trees out of view. Several birds over that direction. 1010. Over below the far BlueCale roost tree a bird popped up who was a ♂ and I believe banded and possibly #234. 1030. After rechecking the storage/roost area, and still hearing some tapping downslope toward the 3 ponded fork in Matrone canyon, I went down to the fork, but did not come across any more birds. 1045. Now returning via the gulch, 2♂ were up in the storage tree but could not be identified. They flew over the gulch to Tregas's side of the canyon at 1050. Meanwhile more drilling continues downslope from The sycamore roost area by invisible birds. 1100. Noone's returned. I'm off-
