The colour ringed bird has a similar combination to the individual seen previously at Mai Po (
http://www.hkbws.org.hk/BBS/view ... &extra=page%3D1) but is a different individual. The colour combination for this bird is Red-Blue-White. Note also that the ring on the right leg on this bird is Red, indicating that it was ringed in 2007. This individual was ringed as a chick in July 2007 at the MTRC mitigation wetland at Lok Ma Chau.
Please remember to keep a look out for any colour ringed that may be around, and report them here.
