1986 Walter D Koenig Melanerpes formicivorus Finch HNHR 21 February 1600. Counted stores: Main Tree: 307 7 590. Sycamore+: 283 7 590. Lots of empty space. It would seem likely that I've long missed the peak at this territory; 600 acorns is not a very many for this group. 22 March *Group Update* J1138. Last seen 30 Sept (Katy); gone 15 Oct → DA 7 Oct ± 1 week. 4 April 645. Ambushed the 1985 nest hole, catching 863 and 9986. We therefore removed 863 and put him in the aviary, as the 1st of the 8 removal experiments for the year. Katy watched immediately afterwards to check and make sure everything was OK. *Group Update* 8542. Last seen 15 Oct., → gone by 22 Jan., → D.A. 3 Dec. ± 1 mon. 81139.
