(23 April)
decent looks at them. First, there do seem to be only 2,
1♂ ub and the other ♂ or /blue still most likely ♂316.
Both are here hawking, greeting each other, drinking out
of tree cavities, and generally at home.
1115. Somebody (possibly ♂DB/W#44-Y) just got displaced here,
1135. After following the ♀ as best I could for 20 minutes and
seeing her left leg quite well I've decided I'm wrong:
she's definitely not ♂316. This bird is ♂M/red #191 from
School Hill!
1150. The ♀ just picked some sort of (large ≈30mm) dark
beetle out of the air at at least 100 ft! Meanwhile, I'm
quite convinced now that she is ♂191 - her bands fit
satisfactorily and the move makes sense. Leaving.
24 April
Purge: ♀431. Last seen here 27 November 1977, but
I will assume she was around until ♂191 moved down,
about 6 March 1978. In fact, no ♂s at all were seen
here between 27 November and 5 April, and possibly there
was a time when none was here. But I don't have good
evidence for that being the case. Disappeared at 6 March ± 1 month.
Add: ♂191. Moved here as adult 6 March 1978.
I will assume, in lack of other evidence, that the unbanded
♂ here is the same one as here all along.
6 May
1700. No birds here and no stores (I did see one old peanut
shell, however - clearly somebody here had been raiding town
at the Pump!).
26 May
1500. None seen here (or at '75 nest tree) in passing.
11 June
1400. Flushed a ♂ (possibly banded) from near here who eventually
