Melanerpes formicivorus
Road 3
5 April Checked "nest" at 1745, still nothing. Added poor egg
mimic (dice) at the same time. Will watch here
tomorrow,
6 April Start 0825 after a foggy morning. ♀265 looking out of the
"nest" hole as I arrive. Don't see anyone else, so they
may be still at roost. Yes, everyone leaves at 0835. Actually,
I see only the core 3 for sure. 0900, ♀265 enters nest
briefly, leaves with a touch of [illegible] wood shavings. Could the
egg die be gone already? 0925, She enters, [illegible] leaves with
nest material again. 0735, ♂184 enters nest very briefly.
Big question: Where are ♂537 + ♂618? Both couldn't have
died since 3 April? Are they wandering together, participating
in a revolution somewhere, or what? 0948, ♂618 shows up
briefly, eats acorn, then flies off up toward PO Hill
End 1000. I still doubt that these guys laid eggs today,
but it sure seems like it should be soon! I'll try tomorrow.
7 April Check nest at 1630, Empty. Meaning ① Dice
was indeed tossed out (I even found it underneath the
top limb of the 2° (Valley Oak) granary. Next!
Since I'm sure I would have seen it in yesterday's
visit, I presume that it was heaved out between 1000
6 April and this afternoon. Tossed within 48 hrs
(I'd guess within 24 hrs)
8 April Start 1200: ♂184 enters nest, tosses sawdust.
♂184 enters 1220. ♀ leaves 1230, ♂ follows immediately,
♂537 + ♂618 FTF, still interested in hole and
I'd bet no eggs yet. End 1235
