Hi Mike
The ringing group has ringed a total of 56 Chinese Pond Herons over the years. Most have either been trapped at Mai Po or have been birds rehabilitated at KFBG. I think the chicks you refer to were a batch of six birds ringed at KFBG in August 2009.
Without having any more details about this ring number, it is not possible for us to know which bird is involved. It could well be one of the chicks which came from the colony, but could also be another bird. It would certainly be interesting to know, because very little is currently known about the movement of Chinese Pond Heron in Hong Kong. To date we have only one ringing recovery - a bird ringed at Mai Po in October 2004 and found dead at the same site two months later. If at any point you are able to get even a partial ring number I may be able to work out the individual involved (but no guarantees!)
