6 Jan Walked up here, 0930. As I walk up, I see 9666
chase a 9NB mildly from the granary. The 9NB flew
to a tree just 10 m from the granary, but 9666 did not
pursue. However, 15 m later the 9NB returned to the granary,
whereupon 9666 chased her again. This provides some
insight into why a new 9 has not immigrated here. Looks
like we could have inbreeding. Also a 9m/ was
nearby during the above chases, and he showed no response
1130 Whoa in the granary together are 9666,
unt/D6rn./Green
and a 9NB! Maybe there is a
new 9! 9666 took a brief peck and ukt at the 9NB,
but then they sat peacefully together for a min before
the 2 banded 99 flew off, and 9NB followed. At worst,
it looked like a domestic squabble.
Otherwise, very slow here. 9 252
confirmed, but that's all. will have to try again later,
and see if this 9 is indeed in the group.
1200, 9NB is back, alone in the granary, looking
very much at home.
