1976 Walter D. Koenig Melanerpes formicivorus Arnold 1 (22 March) storage tree where they both landed waking and proceeded to eat some acorn bits. The ♂ was in the tree also. 1043. While eating an acorn, first 1 and then 2 unbanded ♂♂ (!) landed near the ♂; one of them walked right up to the Adult and sat next to him just like a juvenile. The adult pecked at the unbanded bird several times, but did not chase him away. 1055. One of the unbanded ♂♂ is now sapsucking in holes over small tree on the laurel storage in the backpart side of the storage tree (Valley Dale). The ♂ is still in the storage tree itself. 1102. Birds ① and ② are now sitting quietly in the storage tree. No others are in view. 1125. I'm not sure what to make of this. Clearly ♂105 has disappeared and been replaced by at least one and possibly 2 unbanded ♂♂. ♂353 is seemingly still here along with ♂199, but the presence of a 2nd unbanded ♂ is unexplainable at the moment, unless he came with the ♀♀ for some reason. Only ♂199 and one of the unbanded ♀♀ are consistently around the storage tree; though some chasing is taking place, none of the other 3 unbanded birds were chased even when relatively intimate with one of the other 2 birds. Hopefully I can ambush some of them here; that and just watching roosting to see how many birds are roosting together will clear things up a little, I hope. Only the banded ♂ provides some semblance of continuity at this point. 1130. Leaving.
