Buckeye
Hastings Reservation
3 January These birds have plenty of acorns in storage at the moment.
The tree is also intact from the storm.
5 April 1150. These birds have lots of stores left. While here, an unbanded ♀
flew to the tree, possibly originally intending to go to a
hole tous in the tree (with luck, they'll nest there and not in
that other hole of theirs).
1155. Unb. ♂ came by. This tree did lose part of a dead limb
this winter, taking 500 holes or so and several hundred
acorns (all of which someone's eaten by now).
17 April 1030. Nobody in any of the known holes here.
23 April 1735. ♀ in the granary, but nobody in any holes.
12 May 1600. Flushed 2 birds from the tree when arriving plus
a third from a very low, easy hole !! Yea! I will need
a short ladder, but otherwise it should be a snap. No sounds
coming from it as yet.
14 May 1600. Opened nest: 4 eggs, incubated (opaque) and dirty:
① 25.3 × 20.9 ③ 25.8 × 21.3
② 26.1 × 21.3 ④ 25.1 × 20.4
These birds definitely do have stores remaining.
24 May 1730. Came by to check the nest, which is empty with
no trace of any babies or shells inside! Birds still have
stores remaining, so maybe they'll try again. Oh well.
9 June 655. 1 bird flushed, possibly from the '75-'76 nest hole.
Nobody in any other holes. Still stores left.
17 June 1715. ♂ in '75-'76 nest hole—unfortunately it is no doubt a
nest. I flushed him (with much difficulty) but was only
possibly able to hear baby noises—is either late incubation or just hatched.
