1977. Walter D. Koenig Melanerpes formicivorus Arnold ! Hastings Reservation 8 October 945. 15' net up in main granary. 1315. I hit the jackpot! 2 unbanded ♀♀!! I processed them as #422 and 423, then released them together. They both flew off at slightly different angles but after a brief stop both flew up to the top of the large VO perch tree just up from the granary where they peaceably greeted 1-2 other birds. Since there was no chasing- at all during the next several minutes, I can be very optimistic indeed about them indeed being the 2 formerly unbanded ♀♀ living (and greeting) here. 24 October 920. Several birds over towards the "Top tree" (the Valley Oak in the center of Al-UA2-LA2-Bianca-Blk Oak) were from here. Seen for sure was ♀ M/LB-Red #422, who flew off over to Al proper. The top tree itself, however, still seems to be inhabited by a flock of unbanded birds picking acorns and occasionally chasing one another. 14 November 930. Bird inside the nest hole 3 December 1530. " " " " again! 18 December Counted stores: 3529. 31 December The toll of the recent storms here was one of their storage limbs; not their largest, but one with 2 snags dead limbs and a fair amount of space. My guess is that they lost in the vicinity of 500 to 600 acorns and probably 1000 holes. Some looked like they had recently been pecked into - possibly they have been using the stores in the downed limb as much as possible. I took a sample of 100 acorns - 35 from the downed limb. No birds were seen.
