Keep Out
Hastings Reservation
29 April 1450. Bird incubating.
30 April 1430. " "
3 May 1145. " " . 2nd bird in granary.
5 May 1700. " " . Flushed out but I heard no baby
wicker cries from inside.
There are, as before, no whole acorns that I can see still
stored in the granary here. (Remember, however, that this
same problem occurred last year when long after I thought
these birds had run out of stores I saw them feeding acorn
bits to their young).
6 May 1530. Flushed bird from hole. Walked over and heard some
barely audible rasps: hatching has/is taking place. Looking
down, in fact, there was an egg (mark #2) directly below
the hole. A small chip in the side was in fact the beginnings
of • pipping by the fully-formed embryo inside. Perhaps he
is the first casualty of the cold, windy, wet weather today
and during the past several days.
10 May 1600. Nobody in hole, nor could I evoke any response from
anything inside. I have little doubt but that the weather
since 6 May (uniformly cold, wet, poor) has done this nest
in. I'll have to wait until I can get the ladder up here to
be sure and to see if anything remains, however.
11 May 1200. Opened the hole: nothing left but ½ an eggshell.
13 May 1315. Nobody seen here at all.
17 May 1650. " " " "
1830. As I slammed the truck door shut I looked over to see
a bird looking out of the lower hole. At least the group is still here!
