Melanerpes formicivorus
HNHR, Monterey Co., Calif.
28 April Noticed on the way up to The Arnold that The ARF granary
(to The R of the road just beyond turnoff to the Lichen enclosure)
has fallen, presumably within the past couple months if not
days.
6 July Eggs in avian nest are undeveloped & infertile.
930. Added a baby (~1000) from Central Canyon to see
if we can get the Lewis' to feed.
950-1150. Videotaped the nest. AWs started feeding almost
immediately and we well into the swing of things by the
end of the watch. No sign of LWs at nest.
7 July The baby is fine.
915-1115. Taped. No sign of LWs.
8 July 800-1000. Taped. One incident of note: at one point,
The unmarked (no whiteout) LW flew almost to the
hole, but was being attacked by an AW who kept
him from landing or even getting remaining in the
vicinity. This was perhaps an attempted visit thwarted
by the AWs? It suggests a potentially useful
manipulation: move the AWs out of the cage and
leave the LWs there by themselves for a bit—maybe
they'll feed? I should try this soon—this one
incident suggests they could be being kept away.
9 July 800. The "white-out"ed LW, who had been hiding in one of the
holes the last 2 days, was dead in the cage this morning with
pecks & blood on his head. Only 1 left.
845-1045. Removed AWs to adjoining cage; left the lone LW
here by himself w/ the baby. No sign of him at the nest,
however, during 1½ hr video taping.
