Melanerpes formicivorus
Plaque
(15 April) then flies off 0811.
Big trouble: I climb up to the branch, and measure
the now broken egg: 25.5 x 17.8 mm. Clearly not
a rutt, and clearly the work of 9496, who threw it out.
Oh Dear: In addition to the puncture, there was
a hairline crack around most of the egg, but I was
able to pick it up, measure it, and put it back on the
branch without destroying it. The only consolation
in all this is that I think I got a nice photo of 9446
leaving the nest with the egg.
0830, I set up the camera for Leslie to take pictures
of birds eating the egg. See her notes for a running
account. At 1030, I return to find egg shell in
two fragments, one large, one small which I photograph.
I then get back in the blind and get one perhaps OK photo
of 521 holding up the large egg fragment before
flying off.
Leslie also reported that 9496 removed more
wood chips during her watch from 0830 - 1030.
This sounds suspiciously like 9496 has not gotten
her act together. We'll see what happens tomorrow.
16 April More weird stuff today at Plaque: 9494 alone
lays, and her egg is thrown out by 521! What is
wrong with these birds, anyway?
0605, watching hole: Checked at 0600, empty.
0615, a starling enters nest hole, I scare him out.
Back in the blind at 0618:
