1979 Ronald L. Munme 3 Melanerpes formicivorus Lower Arnold 2 Hastings Reservation (26 Aug) but at 1230 I saw 6 birds together in the LA2 granary (Blue Oak). I was able to read the bands of 5, ♂321 Orange/ D Blue-Yellow (N), ♂426 Black/Orange, ♀320 Red-Green/Metal, juv 497 Metal/Black-Red, and ♂102 Yellow/White. The 6th bird was a ♀, and presumed ♀427. 30 Aug Start watch 1045. An unbanded ♂ in the granary, working a Blue Oak acorn. He gathered the acorn from a tree loaded with acorns, in the ravine to the west of the granary. The loaded Blue oak is close to the field. 1100, now an unbanded ♀ in the granary. A few moments ago, the NBO flew west to the large Valley Oak at the edge of the field, just east of UA3 (see map on back). Promptly chased by a presumed A3-4A2 bird. Same tree where much revolution action centered on 26 Aug. 1115, ♂+♀ looking, fairly cozy, in granary together. ♂ harvests a couple more Blue Oak acorns. Starts working, flies off. ♀ then starts working, the acorns the ♂ harvested. Is this common, ♂ harvesting, than giving way to♀♀? Saw it at A3 the otherday, Looking up, now I see the ♂ back working those acorns. 1120, ♂ digs around in the storage holes (refurbishment?). End watch 1150 9 Sept Everytime I come here, something different is happening. 1000, an UB♂ plus a banded ♀ which I read as D Blue/Red. That would point to ♀507, the former resident here! Where has she been the last 2-3 weeks? Later here for roosting. Zilch! 28 Oct Flushed 2 birds from the granary, A modest amount (~200) of acorns stored.
