Melanerpes formicivorus
Black Oak
(15 October)
900. Absolutely no sign of anyone here until I started counting
acorns and 1 bird sat briefly in the upper perch tree. Where are
they all?
Stores: 507, all in central area.
930
1030. Walked down to the dead limb at the far low edge of the territory
where, lo and behold, there are some birds! ①♂ Or/?? (Kw) #321;
②♀ Yel/Wn #102; ③♀ Red/M #427. Birds are eating acorns down here.
1045. A big dominance fight over something; ③321>>④427.
④♂ LP/Dg-Lg #428.
1015. Both ①102 and ③428 now in perch area over toward
Branca from the central storage area here.
9 November
1010. Watching.
1035. ①♂ Wn/Yel #102 in perch tree (and has been since 1010).
1050. 1 bird flushed from the low snag; not much activity there,
either.
1120. ③102 back alone in perch tree.
1140. ③102 still here, but otherwise the place is deserted.
I'll no longer count on any of the babies being around.
Hey- an adult ♀ just joined him up there: ③♀ Pk/Red #427.
1200. ③428 apparently seen with another bird on the far
edge of Branca (see Branca notes).
30 November
Purge: ③426, ③410, ④320. All last seen on 21 May,
all gone by 29 July → Dis. abt. 24 June ± 1 month.
In addition, it looks bad for the babies (all 5!) but I'll
give it another watch before giving up on all of them.
9 December
1040. Watching. None found in a walk around the area. Also,
the entire top of the "Hanging Limb tree" has fallen (no holes lost, however).
