Dear Alan,
Many thanks for these valuable sightings.
I will discuss your sightings with others (who may have an opinion on
the matter!), but I think it is most likely that the 'dark blue' you
report is actually black, and that therefore the Great Knot is from
Chongming Dao rather than Japan.
The reasons I think this are many: firstly, you mention two different
colours of blue, while Japan use the same blue on all birds. There
should be little difference in colour between any two genuinely blue
flags.
Secondly, the 'dark blue' over white flags were on the right leg, while
Japan typically flag on the left leg.
Thirdly, there are many sightings of Great Knot from Chongming Dao, and
none or very few from Japan. This corresponds to the difference in
numbers flagged in each region.
Once I have sought further opinions, I will 'process' the sightings and
send out a 'formal' report with details of the minimum distance, and
direction, the birds have moved.
All the best, and thanks again

Subject: Flagged Waders in Cairns
Last Sunday, 25/03/07 Birds Australia North Queensland Group and various
members of the public gathered to 'Wave the Waders Goodbye". Among the
observed birds were two with flags.
A Great Knot had dark blue over white flags on the right leg.
A Grey-tailed Tattler had mid blue on the left leg. This had some
inscription but we could not read it.
I presume that both these birds were banded in Japan and it was fitting
that
a Japanese born member found them both.
