Melanerpes formicivorus
Black Oak
Hastings Reservation
(29 July)
2030. These birds are roosting in a PoisonOak-covered trunk in a hole
pointing upwards. Maybe it's a good thing I didn't find the nest (which
was probably here); I would have killed myself getting to it.
30 July
1900-2000. Made my way through the Poison Oak by cutting
it branch by branch until I was able to reach the hole.
31 July
As far as I could tell 2 birds roosted in the hole this evening.
19 August
1430. 4-5 birds here, inc. 1 juv, 2♂, and 2♀ for #197.
1605. See Braica notes for discussion of several Braica
birds sitting in the lower part of the territory here. Meanwhile,
4 of those birds were in the upper section (nest area and
perch tree toward LAZ), where I saw 2 unring juveniles
and 2 adults.
31 August
1815. 8♂102 in forest toward LAZ. Meanwhile, in the far bottom edge
of this territory were 2 birds, a ♀ and an [illegible] unring ♂, who
were sitting in an old storage tree down there (see map). The
♂ climbed up and drummed once while checking me out; I
assume these were Black Oak birds.
I also counted stores: main area: 483 ? 508
Edge 25 ?

930. Net up. No catch.
9 October
900. Net up. Watching from hide.
902. A bird just got displaced by another AW (♂) in the central
storage area.
The flies are incredibly bad today!
912. ♂-type; very possibly juv., up in forest perch area.
925. Another ♂ub, this one certainly an adult.
930. This time the ub bird in the forest perch area was ♀-type with
