Melanerpes formicivorus

(30 April) Outside, I flush them out, and they fly off in a very
tight pack of 3. I go up to the "nest" and find (once again)
no eggs. But the bottom has a much nicer cushion of wood
chips than I remember from past checks
1520, watching for awhile here. ♂♂ still definitely hot
following the ♀. May even be showing more tight packing than
previously. ♀601 is missing again
4 may Nest check at 1700. Of course, the nest still has no
eggs, even though I've been seeing birds in or at the hole
virtually constantly. However, the bottom is now very nice
and well cushioned. Tomorrow?
5 may Introduce 2 eggs to the nest at 0615, trying to get
egg-tossing photo. At 0635, ♀ entered, followed closely
by first one ♂, then another. 0710, everybody leaves
Nest check 0830. 2 fake eggs, plus one real one. (#1)
She finally laid today, but did not throw out the
two plaster eggs beforehand. Hmm! Why didn't she?
Could she have had to lay at exactly that time, no
later? Anyway, egg #1 laid 5 may, about 0640.
Watching 1720 ♀601 metal/war-creeper here, after
along absence at @1755, all 4 birds in top of granary, both
♂♂ peck hard at ♀601.
Watched until roosting, when I'm pretty sure all 3 cone
birds roosted in the nest. The ♀ went in very early, and
the two males just flew around the hole after that. Saw
pre-roost mounting between the ♂♂ (with no aggression)
Late, I saw ♀519 fly to a ♂ and give a precopulatory
