1977 Walter D. Koenig 8 Melanerpes formicivorus Arnold 3 (8 October) Hastings Reservation 1203. ♂♂ Red/DB-yl(n) #121 sitting here in '77 nest tree for several minutes, then flew off towards UA2. 1209. Some activity heralded a Cal Ground Squirrel (big) walking around up in the granary. 6 of the ATs were quite upset, and would fly over and hit the beast, apparently with their feet and claws, up to 2 or 3 times in rapid succession before landing one or two feet away. All six took turns at this barrage. The squirrel, however, seemed relatively non-plussed by the whole event, and continued sniffing around at storage holes for 800s a minute before he finally disappeared into a hole in a rotten limb. 1210. ♂ 121 in granary now! 1215. Leaving. Looks good - all banded birds are here except for ♂205, whose disappearance doesn't seem improbable. No unbanded birds were seen at all! The disappearance seems too good to be true for the moment however. Obviously the biggest problem now is to find out who's still living at UA2 and who's moved to LA2. 1225. Flash: ♂ a ♂ with a hurt left leg and a M band on left leg - most likely ♂122. What's going on down at LA2 I wonder? As for here, the birds are quite active and are storing a lot. 1230. ♂126 here again for sure in granary. Squirrel came out to be similarly attacked twice more. 6 November Purge: ♂122, moved to watched group (LA2) about 25 Sept. ± 1 wk. 14 November 1128. Watching. 1145. ♂♀yl/m #128 and ♂♀or/db/or #289 in granary together. ♂♀DB-wh(m)/DB#270
