Hi Stephen,
I recently saw a similar sized group of CPs with 2 members of the
group doing similar lying on-side, briefly flicking up a wing while
the rest of the group went about its business. It was sprinkling rain
at the time and I thought the birds were just engaging in some kind of
bathing activity. Your having seen CPs doing the same when it was dry,
now makes me think perhaps otherwise. Interesting behaviour, will have
to keep an eye open for CPs doing similar and have a closer look.
Hopefully I will have my DSLR with me and will be able to take a movie
of it and study what they are doing more closely.
Cheers,
Carl Clifford

Yesterday I saw a small flock of Crested Pigeons (about 6 birds from
memory)
in an open grassed area. One pigeon was lying on its side on the ground,
flicking one wing upwards, so that the undersurface of the wing was
exposed
for about seconds with each flick. The other Crested Pigeons did not
seem to
react, continuing to forage around the displaying bird. I thought at
first
that the bird lying on its side was dead or injured and that the wind
was
catching the wing and blowing it upward. But as I approached the flock
on
foot all the birds, including the "wing flicker" flew to a nearby tree.
So I then thought I had observed some form of courtship display, but
there
is no mention of this behavior in HANZAB. Has anyone else observed this
behavior in Crested Pigeons? I'm also interested to hear other peoples'
views on the purpose of the display.
