Sorry - I put the comment that should be here on your entry! There must be lots of different cormorants (the one I showed is actually a flightless one from the Galapagos), but all the ones I have seen have been basically black - but do have that wonderful iridescent sheen if the light is right.

George.....this is something that I would love to photograph. I think I have been inspired by the HSBC advert! I have read that these birds are looked after well by their owners as obviously they are their livelihood (hoping this is correct), however, have also read that they tie string around the birds throats to stop them swallowing the fish. Don't know if this is true.

The birds in Guilin do have a band round their necks when fishing, as otherwise they WOULD just swallow the fish! They are normally operated in pairs on a stick, as in this picture of a junior tourist!
