(27 April) just as abruptly zooming off (again in a karrit-flurry)
over in the direction of the nest hole. Thus 2 birds
apparently roosted in each.
1 May Watched here this evening after checking over at the
hole again and finding noone in attendance. The nest
is almost certainly defunct, in any case, as for once
all 4 birds roosted in the same hole (one of the granary
holes). No sign of a 5th bird.
7 May 1530. Opened the low hole in the granary, where Ron said they
were probably incubating, and found 7 (!!) eggs!
8 May 1930. Watched roosting here. When I arrived at about 1905
I flushed 3 birds from the granary (not the hole) but
that's the last I saw of any one. Unless the 4th bird
was in the nest the entire time, noone roosted in it.
(Same thing happened last night, see Gwen's notes).
10 May Watched here in the early evening; both a ♂ and a ♀ were
in the hole most of the time, but I never saw any visits or
identified the birds that were here. However, they were clearly
incubating.
11 May Gwen came up here this morning and failed to see anything
going on at the nest.
12 May This afternoon I came up to watch with the same result,
as the 10th - a ♂ and ♀ were in the hole for nearly an hour;
then left, but nobody ever visited the hole. So I checked the
hole (still 7 eggs) then went down and brought up a real hide
from which we can hopefully get some data here.
13 May Watched the nest for 3 hrs this morning; again with only poor
