1980 Walter D. Koenig
Melanerpes formicivorus
Valhalla Hastings Reservation
8 January Purge: $519. Moved to watched group on 28 December 1979. At present, the status of this group is unclear. (See Westgate notes for more information on $519).
20 January 1120. One bird in nest tree began to karit-cut vigorously when I came up here: $\alpha/\gamma$ see #501 from Finch (!) The bird continued to display for several minutes and then finally left. Meanwhile, there are still stores here, but there was no sign of anyone else. $222$ is most likely gone, I'd say.
2 February 1445. There are still some stores here - perhaps 100 or so. However, I saw no sign of anyone in passing, and I have to wonder whether or not anyone lives here any more or not.
23 February 1315. Stores are diminishing rapidly here - there are possibly 25 or so more left. Meanwhile, there were several birds up in the trees where the Valhalla birds tended to hang out. These birds were mostly hawking, and turned out to be the R1 birds (3 of them at least).
$222$ is surely gone, and this territory would appear to be up for grabs at the moment.
21 March Purge: $222$. Last seen here, with $519$, on 5 Nov. 79. On 18 Dec. I flushed 1 bird and found nearly 400 acorns here, but by 28 Dec. $519$ had departed for Gate. Unfortunately I have no idea whether the $\alpha$ disappeared, followed by the $\gamma$ abandoning, or the $\gamma$ abandoned, followed by the $\alpha$ abandoning. Since noone was here by 20 Jan, I will assume the former; thus → Disappeared about 1 Dec. 1979 ± 2 wks. $519$ should then be changed to Abandoned about [seen again]. This territory is presently up for grabs.
