Chocky, interesting looking bird. Never having seen one, nor heard the name and being the curious type that I am by nature...I googled it and found the following for us across the pond - interesting on its relationship to cormorants. http://en.wikipedia.org/wiki/Cormorant
Thank you for your comments
Yes they are slightly smaller that Cormorants and in breading season the mail has a nice crest .
These birds are all related to the Pelican
