(25 April) and Gwen have failed to see anybody incubate. Thus, I came
up, flushing 2 birds from the granary (I possibly from the low
hole) and checked the nest hole (nobody in it, however). All 6
eggs were still there, but they are stone cold. So I went up
and checked the low hole in the granary, also. It was empty,
but in good shape.
Thus, my guess is that these birds have abandoned the nest, or,
at the very least, are rather nonchalant about incubating.
We'd better keep an eye out here, since things are probably not
settled yet.
27 April 1915. Came up at dusk to try and see what's up here.
First of all, checking the nest, there was once again no sign
of activity, thus supporting the failed nest hypothesis. I
then returned to the granary and watched. At about 1910,
the birds - 4 of them - suddenly appeared. Although they
didn't appear to all arrive at once, they were all in the
granary within 30 sec. of each other. After a short stint of
kanitcuts they assembled together on a limb, each only a few
inches from the nest. After a brief tense moment one appeared
made a move [illegible] and briefly mounted a second
bird, but the mounting was broken up in a flash and all
4 birds zipped off in a very tight pack to a 2nd limb. They
all stayed there for another 30s or so until several
zipped up to a (hitherto unknown) roost hole. Two went
in, a 3rd hung around briefly before flying off in a kanit
flurry toward the nest tree area. The 4th stayed out a little
longer before going to the roost hole, entering it, and then
