4 June
825. Flushed one bird from the storage tree, who flew and landed
silently somewhere in the forest between there and the knoll.
Now watching from the hill.
837. Pub in storage tree pecking at holes.
839. 9 flew to blue oaks just toward knoll, greeting another bird.
841. 9 162 in storage tree hawking. Pub here hawking also.
842. Both gone.
855. Both back again
915. Now both gone into forest again.
925. My distinct impression is that the patterns shown here indicate
that this group is not breeding, and the reason is that the adult 9 is
gone, having left only the adult 9 and her son from last year,
a pairing which I suspect is non-viable. Activity is clearly
being split between the storage tree and the mostly uncharted
forest between there and Blon Knoll, a small but hard to watch
area without holes to my knowledge. In any case, both birds show
up, often simultaneously, at the storage area to flycatch or sit
and there is no indication that they are saving what they catch
or taking it anywhere in particular; surely incubation is not
in progress unless, of course, that's where the 9 has been the
last several weeks.
8 June
930. Watching
935. Some calls heard.
937. 9 came to storage tree briefly to chase away a Mourning
Dove, then flew down into forest toward Blon Knoll.
950. Pub in storage tree again; moved acorn, then began hawking.
1000-1030. Pub in storage tree, mostly sitting and preening. A 2nd bird heard.
She seemed in no hurry to feed anybody or get anywhere.
