26 May Nest check 1130. No hatching yet.
27 May Checked the nest at 0715. Eggs (3), (4), x (5) had hatched,
the 3 small nestlings were marked with ink on the right heel
pad. Egg (2) appeared to be pipper, ad egg (1), the near

that hatching occurred between late yesterday ar today,

2 nestlings for both P523 x P524

report of no feedings in 3 hrs yesterday, I check the nest
to find the grim remain (well decomposed) of #700, but the
remains of no other birds (!). I would suspect partial predation
(weasel, fox, or what?), resulting in #700 being killed or the
nest being abandoned. The group still has acorns, ad even if
