Melanerpes formicivorus
Plaque
14 April Checked the hole [illegible], 1415 (Walter found
5 eggs 13 April). 6 eggs. Is the clutch
now complete?
15 April Checked the nest, 1630: Still 6 eggs. Probably
all over here.
18 April Walter removes the 6 eggs from the nest here.
26 April Return from Berkeley today + Denise reports
that while watching the Plaque nest hole today,
She saw a Q fly out at 0628 (early!) carrying
an egg. Unfortunately, we don't know who
laid it or who threw it out. Unfortunate, but
maybe we'll be lucky tomorrow. See Phillip
+ Denise's notes. Phillip checked the hole
found it empty sometime yesterday morning. See Philip
+ Denise's notes for details.
27 April Good watch at Plague! Basically, both Q laid simultaneously
between 0650 and 0720, 1 normal egg, one runt.
I measured the eggs + I'm confident that the normal
egg (27.2 x 20.3) was laid by Q494 (see past-years
egg dimensions) and the long narrow runt laid by Q496
(21.2 x 14.8) Q496 always lays long, skinny
eggs, and never has laid an egg wider than 20 mm.
Anyway, Phillip I watched more, Q496 removed
both eggs, the runt first at ~ 0850 [illegible] followed
by the normal egg ~ 1020. See Phillips notes
for exact details. I saw a bird fly out with
the runt egg ~ 0950, whereupon it was carried to
