(17 February) My next move should be to try and catch this ♂ to see if
he's hanging around here regularly.
1230. Set up some netting around the captive, but was unable
to catch the ♂, who remained in the tree pretty much continuously
until I left at 1400 forgood.
In an attempt to draw some conclusions concerning
the fate of this group, I here summarize all sightings
since May, when I still knew what was going on:
May. ♂ub, ♂ub, ♂162 (end of first yr) seen repeatedly.
4 June. ♂ub, ♂162 seen only. ♂ub suspected to be gone.
July. ♂ub, ♂162 still only 2 present.
5 August. ♂ub now here, along with ♂ub and ♂162.
[Surely not the same bird!]
11 September. Many birds here (288, 299). Some
chasing. ♂162 not seen.
15 September. Still several strange birds here. One ♂ub
captured and banded (♂318), but never seen again.
28 September. Nobody seemed to be here at all.
10 October. Very few stored acorns; a ♂ub and ♀ub here.
Several more watches in October and early November
yield a ♂ub and ♀ub regularly; also, a 2nd ♂ub,
clearly subordinate to the first, was present occasionally
16 November. ♂ub caught and banded (♂323). ♀ub here.
December. ♂323 here regularly; 2nd ♂(ub) occasionally.
17 January. ♂323 here maybe. Stoves gone.
25 January. ♂323 gone; ♂ub seen here.
17 February. ♂ub here alone.
