Hastings Reservation
(11 May) the nest, finding an unchanged 7 eggs.
1930. Returned to watch at dusk in an attempt to find out
which 8 roosts with the eggs, but the same 8 who was in the
hole when I arrived at 1900 stayed in the whole time
with no visits from the outside at all. Earlier next time!!
1934. A brief visit by somebody (it's dark!) but the bird
flew off right away (after making sure someone else was
inside already maybe?)
12 May
1840. Watching nest for their "rooster" again.
1850. 8 left nest.
1855. 8 173 in.
1910. 8 173 out
1912. 8 171 in.
1935. 2nd 8 (173) in; 1 8 out. Argh.
1936. 2nd 8 came to nest, called, got an answer ("Yes, I'm
here") tipped in, left.
1937. 2nd 8 returned again ("Are you sure you're ok?")
(Yes yes, I'm fine") seemed to get merely a "chatter" from the
bird inside, then left.
Foiled again.
17 May
1040. Bird at hole.
18 May
Tried to pin down who roosts in the nest again tonight, but
once again there was little hope, with the last bird coming
in at 1930. Only one did roost in the nest, however:
21 May
1415. Opened the hole, first pulling out 8 247, who was in brooding the
5 babies and 2 infertile eggs. 1 of the babies was clearly starving and
almost dead. Both infertile eggs were taken; both were "normal" sized.
