1982 R.C. Munne Melanerpes formicivorus 1500 7 Jan Watching here 1430. Looks like birds may be harvesting acorns still from the 1500 draw area. Anyway, complete census. ♂297, ♂622, ♀601, ♂675 ♂676, ♂677 all seen. 12 Jan ** GROUP UPDATE ** ① J678 disappeared about 5 Sept ± 2 weeks Last seen 20 Aug 1981 at Bloinquist, but missing from there 12 + 14 Sept and from 1500 14 sept and certainly gone by 30 Sept. 9 Feb Counted stores, 1330: 2° Valley Oak 500 1° granary 1830 2330 TOTAL Also took a sample of about 35 acorns from the secondary granary. A lot of Blue Oak acorns, (one of few groups with any, that I've seen), plus Valley & Live. 8 March Very strange happenings here, 1100. First, lots of intruders and chasing: Alan had been watching at 1800 and reported intruders there. Here we see 2♀ NB in the ☐ Sridge, above the granary. We then get a full census (♂297, ♂622, ♀601, ♀675, 676, ♂677), but then we notice that ♀601 seems to be getting chased by her own group member! She now seems to be excluded from the granary, and is hanging out on the ridge area. Once it appeared that ♀601 was being chased by a ♂ (!) 1145, Big Chase! 2 birds chase hell out of ♂601 for about 30 seconds, all over the territory. Don't know who, but it was definitely NOT ♂297 or ♂622, as I had them in sight 1150, Alan reports ♂676 definitely chased ♀601 from the Knoll trees
