It’s a Great Cormorant but hands up if you understand and can interpret gular pouch angles to determine the sub-species. Well this is my best shot of which I’m not certain. I measured the angle on this bird as 72 degrees; however this varied between 67 and 72 degrees depending on the angle of shot and which side of the head you chose.

These angles fall into the grey and overlapping area between the 2 sub-species and as far as I can ascertain a positive ID to that level is unsafe from a photograph. So for me, it remains as a Great Cormorant.
