Melanerpes formicivorus
School Hill
(3 September)
1808. 886 flew off.
1809. 8402 flew off in same direction; only ♀ remains.
1810. 886 back here below the ♀. 886 eating acorn ~6' below the ♀.
→
1814. 8402 returned. Hopped up trunk to ♀. Hopped on back of
♀ in pre-roost mounting. 886 here immediately. ♀ moved away
after only 1 sec. or so. Now ♀ below 8402 who is below 886.
1827. ♀ flew down and off.
→
1834. Both 88's flew off simultaneously. All are now lost.

Later at 1845 I happened to see all 3 birds fly by
me in a "pack" while over in the canyon where we thought
they might be roosting. They appeared to be headed toward
the field. Back up there, none was in evidence, nor was
anyone in any of the roost/nest holes. Nor could I find
anyone back down by the wagon road. Thus, their roost hole
remains a mystery. Also, it would appear as though incubation
has not begun as yet.

645. 8402 at Y looking interested. See Y notes.
700-915. Watched the nest but saw almost nothing. 886
was in when I arrived looking out at me - a position
he maintained for 31 minutes before leaving. Later the
♀ (9260) sat at the lip for a minute, but flew off without
tentering. That was it.
At 9:30 I checked the nest with my mirror and found
all 3 eggs intact with no obvious hatching activity as yet.
1815. Returned at dusk to 1) check eggs (still 3, no sign of
hatching) and 2) watch roosting. (886 roosted in nest for sure).
14 September
Watched the nest from 800-1030 - see back. Also checked
