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disappeared and been replaced by at least one and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.
