I agree with Sze that the bird is A39. It has been reported that the white band has turned yellow in 2009.
This is the 4th consecutive year for this bird to come to Mai Po for wintering since it being injured from fish hook, recovered and released in March 2008.
Very happy to see it still in good health!
