Sorry to continue this debate, but I have just returned from Broome where I
participated in a wader banding expedition... Some points from Kym's notes
above that need to be corrected :
1. Waders are banded with a metal band on the left tarsus (lower
leg). Kym, you did not see the metal band.
2. The leg flag is always placed on the right tibia (upper leg). You claim
the flag was on the left tibia.
3. You claim that 50,000+ Curlew Sandpipers have been leg flagged in the
past few years. Please quote your source for this. There are not this
many birds flagged in a year across all species in the world. We caught
about 3,700 waders in 4 weeks in the north west. Several hundred of these
were retraps and the 1st year godwits and knots in Broome were given a
yellow cohort colour band in place of the leg flag, so we put about 3,000
to 3,200 flags on the birds. This is the biggest flagging effort done for
12 months. About 100 of these were Curlew Sandpipers. So your 50,000+
claim cannot be supported by any possible facts. Certainly, more than 100
are flagged in Victoria, but certainly less than 1,000 a year. Leg
flagging did not commence until about 1992.

week of October. I can't see why Victoria and South Australia would be any
earlier, as the adult birds land in northern Australia in August/September
and refuel before moving on south. Maybe this is why you don't see the leg
As for those worried about the effect of a leg flag on a swimming
Red-necked Phalarope, the weight of the metal band plus flag is about
0.2grams. The flag freely rotates on the upper leg. So its affect on the
bird is 3/5 of 5/8 of .... all.
On the recent expedition, we caught two Grey-tailed Tattlers with Taiwanese
bands on 80 Mile Beach. The first was banded in 1988, and so is a 15+ year
old bird. The second with a white leg flag over a blue leg flag was banded
in August 2000, and so is a 3+ year old bird. Taiwan has only leg flagged
about 50 Grey-tailed Tattlers so this is an outstanding recovery.
