All acorns from yesterday (8 July) gone July 10 0700 - 1000 Arriving found 2 birds in granary. Set up for Power Struggle, but tape would not come on very loud. 0745 Caught and banded ♂ 1131 68.5 (142) 0900 Identified all Warp 5 birds (636, 5177, 997, 998, 999) The ♂ and the babies spent quite a bit of time attacking the ♂ dummy (even after the tape ran out) They finally succeeded in breaking its head off. The ♀ was not seen to attack this dummy, though she seemed "interested" in the attacks. She showed particular interest in the ♀ dummy, though neither she, the ♂, nor the babies attacked it, possibly because it was partially tangled in the net and attached to the speaker. Acorns taken from the granary were either eaten there or taken to Warp 5 (or at least in that direction. About 0900 an unbanded ♀ (not the Warp 5 ♀) appeared on the eastern edge of the clearing, but did not approach the granary, left 10 min later. 18,19 Aug some acorns(mine) there. No birds
