1976 Walter D. Koening Melanerpes formicivorus Road 1 Hastings Reservation (9 August) landed here; #69 still sitting on the other side of the tree. 1016. @BPRW#227 down below in the sycamore. 1018. @♀ Red-wh/LP #180 in view in the granary. @BPRW#181 down below @♂ORLW#182. 1030. Within 15-20 seconds 5-6 birds had congregated atop the storage tree, including 2 j-u-ws, #181, #72, #66, and #ub(?). #181 and the j-u-ws chattered loudly and constantly in submissive behavior, but this did not keep the adult ♀ from pecking mercilessly at the j-u-ws. However, even as one was doing so, as a third bird came up behind them the attacker would stop and chatter briefly in a flanker display of appeasement to the approaching bird. Thus, for several minutes, a great deal of chattering, some wing-flap begging, pecking, and even one grapple was taking place here among the heterogeneous mix of group members all briefly in one place here. 1125. j294 back in storage tree eating an acorn (from the stores). 1145. #69 still here hawking; others down below by the creek and nest tree 1200. j293 working stores and eating an acorn here by himself. 1225. Leaving; nothing new. Down between the nest tree and the creek is @♂BPRW#183. 11 August Purge: j291, j292, not seen after banding on 10 June 1976. 1 September 1000.
