(9 May) 110D. Nobody's returned to the suspect tree, best I can tell.
Maybe they haven't started yet after all.
1715. Bird in hole! We got it! Must have eggs still.
12 May 1500. Opened Hole: 3 eggs; 2 opaque (incubated at least
several days), 1 not developing, apparently.
20 May 1900. 2 babies, 1 unhatched egg. Wts: 13.5; 12.2 gm.
(≈3 do; hatched ~17 May)
(5.1285
in nest)
1940. Watched roosting here: 3(285) (8M/2-W(N)) roosted
in the nest by himself.
3 June 2000. None roosting in the nest, presumably at least in part
due to Stanback's T implants. Bird in hole when Val arrived to roost watch
1 July 1500. No stores left, best I can tell.
25 August 1400. Opened the spring nest, where there are 3 babies!
① 51.6 (28)
② 53.2 (30)
③ 53.0 (27) [≈13 do
Est LED=1 Aug]
This group has not been supplemented since 15 July, but
may have been given some food...
But note: There are some blue oaks already dropping
acorns right nearby - could these early trees (many of
whose acorns are largely damaged) have prompted this?
4 September 1130. Banded the 3 babies here. (See capture records for
measurements).
