27 April the afternoon here. Pretty routine stuff, seeing
all but ♂294 in the nest. Today, though
♀383 replaced ♀269 at least a few times.
Back here at roosting, and it was back to regular.
Near dark, ♀269 was in when ♂294 came and entered.
A few minutes later, ♂486 came, the other two birds left,
and ♂486 roosted.
28 April A combination nest ad group watch from PG hill in between
raindrops. A brief possible dominance interaction.
The 2 ♀♀ were on the secondary sycamore granary
alone, when I thought ♀269 gave a gentle peck to
♀383. ♂486 seemed to disappear towards the end of
the second watch. I hope he's OK.
29 April Roosting only tonight, and although I have a few doubts,
I am pretty sure a saw metal, meaning ♂486 roosted
30 April A pretty routine nest watch here, with nothing much to
write home about. I also gathered some more pairing
data (below). (Page 11)
Back at roosting, ♂486 was in as I arrived, then
♂294 entered. One left, and although I think it was ♂294
that left, I couldn't be sure.
2 May A nest watch here, and the eggs have hatched!
Birds bringing insects, and even ♂294 put in a brief
appearance!
3 May Roosting here. I managed to fog up my scope at exactly
the wrong moment, but I think it was ♂486 that
roosted.
