Melanerpes formicivorus
Road 1 Hastings Reservation
(17 September) 1615. Back now. All seems pretty quiet.
2 November 130. Counted stores: Main tree: 431. (None seen elsewhere).
Those birds aren't really into it yet, apparently.
5 November 1015. Watching from hide.
1021. ① ♀ DB-wht (ch)/Wht #269 in Valley Oak up toward Valhalla.
1040. Second ♀ here with ♂269: ② ♀ yel-bk/yel #383 from
R3! Both ♀♀ now in granary working stores.
1045. ③♂ or /DB-yel #294 in sycamore perch tree.
1100. ♀383 still here looking quite at home. The birds are
flitting around a fair amount but do not seem to be storing
any acorns to speak of.
1200. Leaving for a quick check of the area. Nobody here now.
No sign of 3486; also, why aren't these birds storing?
9 November 1100. Watching again from the hide.
1105. All (?) 3 birds together in Valley Oak up behind me: ①♂ Or/DB-wht#294,
② ♀ yel-da/yel #383, ③ ♂m, #269.
130. Well. This was not a lengthy watch but the results are
nonetheless consistent with the hypothesis that 3486 is
kerplut. Leaving. Still no sign of large-scale storing.
18 December 1400. Counted stores: Main tree: 1085
Other: 144
Not bad, but still plenty of room for more, I'd say.
I took a sample of ~65 acorns from the granary and replaced
them with some of my own. In doing so I noted a lot of acorns
stored in cracks - at least 150-200 in the area I was checking out.
I would therefore guess that this group is somewhat better off than
my count indicates.
