Melanerpes formicivorus
Warp 5
Hastings Reservation
8 May
1215. Checked around here, finding lots of nice looking trees,
but no promising holes. However, there are stoves left here,
so they no doubt have a nest somewhere.
9 May
1200. Walked through here, seeing one bird in the granary fly off
around the hillside (toward Gate). But otherwise we found no
new good looking holes.
17 May
1030. Checked everything I could find here with notably
little success. I did recall and check a nice hole in a
Black Oak on the ridge toward Velhalla, but I didn't
see anything terribly promising there.
4 July
Coming up here to check roosting we flushed 3 birds from
the hole in the Black Oak, at least one of whom was a baby
from the call it made (Ron had seen fledglings here following
adults awhile back). Eventually I may get these birds.
(Ron is pretty sure there are 2♂♂ and 1♀ here, all unbanded).
23 July
Set up an ambush here (at the lower hole in the Black Oak).
Ron watched this evening and reported a total of 6 birds (!),
4 of whom roosted in the hole. So, apparently this group
consists of 2 adult ♂♂, 1 adult ♀, plus 3 babies from this year.
24 July
630. The ambush was a success, netting 2 adult ♂♂ (8628
and 8630) an adult ♀ (8629) and 1 baby, who had just
started her post-juvenal molt and is going to turn into a
♀ (8631). Now all we have to do is find their other hole
and get the other 2 babies! [3! see below: apparently they fledged ?4 here]
28 December
900. An ambush at the same hole as before yielded another 4
birds, only one of which (8629) was banded! The others (1♀
and 2♂) were all apparent 1st yr (wearing mainly) and are now #633-635.
