Melanerpes formicivorus
Plaque
(16April)
0710, ♀494 lands at hole, enters immediately:
0712, ♂521 looks in, enters: Both ♂521, ♀494 in
hole together. ♂473 looks in for 30 sec, flies off
without entering. 0716, I hear tapping from inside hole.
0716: Uh-Oh, ♀496 enters the hole; 3 birds
all down inside hole
0719 ♂521 looks out. 0722, One of the ♀
leaves with wood chips. Judging by the fact that this
♀ was not followed from the nest by ♂521, and by
the fact that ♀496 has been removing a lot of wood
chips the last few days, I'd say ♀496 left at 0722,
♂521 continues to look out.
All 0724: ♂521 leaves, second ♀ (♀494?) looks
out. She has a very thin black line from the closure
of the bill through the white bar of the face. She leaves 0724,
too:
Checked hole by peeping: Anot unexpected new egg:
There is some doubt about ownership, since both ♀♀ were
in the hole while it was laid: But I'm fairly certain
it was ♀494's for the following reasons:
① This egg, ever by peeper, was definitely shorter +
rounder than yesterdays egg. (♀494's eggs are usually
not as long + narrow as ♀496's). Definitely not a raut!
② ♀494 entered first + (presumably) left last.
③ ♀496 has been removing wood chips, Behavior
not appropriate for a laying ♀.
0728 Back in the blind.
