Melanerpes formicivorus
Many Plaque
(27 April) the main granary. This bird proved to be 9496,
and I saw her eat some of the egg for about
1-2 min before flying off.
Philip reports that 9496 took the normal egg
to the main granary, but wasn't sure what
happened after that
28 April Boring egg-laying watch at Plague. A ? (9496?)
was in the hole when F arrived at 0615, and after she
left at 0627, F climbed up to the hole & found
a 9496-shaped egg (25.4 x 18.4). Nobody
returned to the hole before 0830, at which
time Denise relieved me.
Is one ? (9494) taking the day off?
Could she have laid elsewhere? (I checked the
82 hole (empty) and Bos Berry told me there was
no woodpecker activity up in the canyon area?)
It's also possible that 9494 laid before 0600
and 9496 threw it out, then laid herself. I'll try to
get here earlier tomorrow to see what time laying
occurs.
1045, Denise has reported both ?Q in the
hole alone twice each, so it looks good that
9494 did not lay today & will not toss 9496's egg.
29 April Good day at Plague! Both ?Q lay (see reverse + nest
record), and yesterday's egg (by 9496) remains, meaning
no reciprocal egg tossing by 9494, even though she
had ample opportunity.
