Melanerpes formicivorus

Hastings Reservation
(11 April) tail twist underneath, good cloacal contact. This time,
?494 was right there watching to both of them, not doing
anything, and ?473 not doing anything to her. She was even
giving the tail raise-wing droop water. I believe that makes 5
copulations between those two birds. 0710, Absolutely no
sign of ?522.
In the big Blue Oak west of the 6bs,
the 4 birds here chased an intruder, which flew toward the
"Y" sycamores. I suspect it was a School Hill ?: Both
were reportedly hanging out there yesterday. 0715, the 2 ??
are really following ?473 around, and are really inviting
mountings. ?476 seems especially "brazen" and "immodest" ?473
seems to refuse most of these offers, but not all. End 0730.
13 April Start watch 1505. Nobody around 1630, Mount exchange
between ?521 + ?494. 1635, ?494 eats tipulid.
Mounting was brief, no cloacal contact. ?496 being
very inconspicuous, staying away from the main area,
1730, Looks like ?521 chasing ?496 some more,
but not completely certain of the participants. 1740, another
very good copulation. ? mounted first, followed by
(5-7 sec)
long, long cloacal contact, tail twist, etc. At a great
distance, could not tell who it was. End 1745.
14 April Start watch 0710. ?496 definitely seems to have problems here.
Did not see her, plus saw chaves up on "Adobe Hill". Only
encouraging sign was that while ?521 + ?494 near
granary, I heard water from Adobe Hill. End 0800
Trying again 0435. Cretins on Buckeye stealing walkers
pack+ rope ladder interrupt us, ?521 still chasing ?496
