Missing from Plague by 6 October ** 10 Feb Counted stores, 1700: utility pole 200 (agurss) 2° tree 350 main granary 1650 2200 TOTAL. These birds have lost more stores, including a deal horizontal "copulation" limb in the 2° granary About 100 acorns, 150 holes or so. Probably fell in early Jan. 11 Feb Collected about 70 acorns from a down limb under the 2° g. The limb came down in early-mid January some time 4 April Counted stores, 1200: utility pole ~50 2° tree 400 1° granary 1010 1460 TOTAL Watched here a bit, 1700 - 1800. Ever saw a slight ♀dom! dominance interaction: ♀494 + ♀496 pecked together in the 2° granary, ♀494 gave ♀496 a couple of gentle pats to the side of the head. Un oh: 1615, looks like definite mate guarding. It seems that both ♂S21 + ♂473 are following ♀494, and neither ♂ seems to give a shit
