1800
(18 April) to happen until 700, when ♂771 came to the hole and looked
it, as if a ♀ were inside. Which, as it happens, one was - but
I completely missed who she was. In any case, ♂771 left
at 707, followed by the ♀ at 709. Since then noone at all
has been to the hole, and (at 800) I'm about to go up and
check it.
800. Well, whoever it was, laid an egg, now marked #1. The nest is on.
(I assume this egg will get tossed sometime today).
19 April
800. Katy watched this morning, but she was gone by the time I
got here to check the nest, which is now empty. So they tossed
out not only yesterday's egg but whatever was laid today.
20 April
The score so far (as of this morning): ♂787 has laid
3 eggs, 2 of which have been tossed (1 by ♀193 for sure).
The 3rd is still in the hole as of this morning. None
(including the one Katy saw tossed yesterday) has been
a runt egg (making me wonder about 17 April - did
she lay then?). See Katy's notes for details.
21 April
Katy watched again today (Mark climbed): yesterday's egg
is gone, ♂787 laid again, not tossed by the time Mark checked.
22 April
Susan watched this morning: both ♀♀ went in (along with
the ♂83) but there were no eggs when I checked.
30 April
1400. Clutch is now complete with 6 eggs. (See nest
record) (my guess is: ♂193 4 eggs, ♂787 2 eggs). Note also
that tossing did not go on as long as it might have - restraint
once again. However! It is now time to let ♂770 go, which
I have now done following a nest check.
1415 Watching the nest.
