(10 May) 1300. Up at the hole, there are still 6 eggs.
12 May 1500. Bird in hole.
13 May 1915. 2 birds in hole. Went up: still 6 eggs.
20 May 1020. Bird in hole.
25 May 1515. Opened hole: 46 babies, 2 eggs. The babies were measured,
etc.; their eyes have not opened yet and the feather papillae on the
most developed have not quite broken the skin yet. The 2 eggs
that failed to hatch were both removed.
Both were later examined, and both did contain forming
embryos - 1 6mm in length and the other 8 mm. So, all
6 eggs were at least fertile.
8 June 1820. Several birds in the nest area; bird in nest hole; may
have flushed a bird from the '75 late nest hole also.
12 June 1400. Banded the 46 babies as #406,407,408, and 409.
13 June 1000. Counted stores: Valley Oak 382 ?
Nest free: 251 / 633
13 July 1440. Watching. (1) PRW#183 and (2) j/or/DP#409 seen on way in.

1510. (4) B/RW#222 also here sapsucking
1513. j409 in perch tree by road with a ♀.
1523. (5) PRed/DB-WN(n) #295 hawking in perch tree. Joined by (6) M/#293.
1530. 2 more babies appeared with j409 in granary: (7) j26-26/M#406
and (8) j46-Br/m#407. One to go...
1532. These 3 babies all together in granary begging from #354.

1550. (9) Pub and another hint of j408: ?(!) LB/Red-Yellow (?) (seen
only very briefly - colors better than sex!)
