Big Tree
Hastings Reservation
25 June
1515. Checked the hole, which has nothing in it in the way of
eggs or wickers.
Purple: 3 108. Last seen 2 Oct. 1977. Inconspicuously
absent during casual watches following that date, but
definitely by 3 May 1978. Disappeared Abt. 16 Jan. 1978 ±3 months.
1905. 3 birds flushed from the low new hole.
3 July
16 July
6 August
A low crashing heard while I was up at Lambert's
waiting for roosting turned out to be the limb with the
new low hole in it!
29 August 1960. Pam saw 4 birds roost here this evening, in the
large Valley Oak roost tree toward A1 from Big Tree.
31 August 1960. Tonight Ron Munne and I watched here, seeing all
4 birds going into one of the known holes. We also saw
some pre-roost mounting by 2 of the birds.
2 September 700. After distinctly watching all 4 birds roost here again
tonight, I ambushed here this morning. Best I could
tell, the gig went off without a hitch. Nonetheless, I've
so far extracted only 3 birds (all banded: 3104, 3403, 3404)
and am now waiting and hoping for the 4th, who typically
enough seems to have escaped somehow.
15 October There are no stores at all here, and probably no longer a group.
5 November Nothing.
30 November Purple: This group abandoned between 2 September and
15 October → Abandoned abt 23 Sept ±2wks (3104, 3403,
3404, and 3406). It is presently empty.
29 December 1345. Sitting quietly in the perch tree here is Bor/lon #199 (A1).
