Thanks volker, thanks Jens, thanks Brett, thanks Jim. I think it's just a large gull but I'd like to think of it as a Blue Footed Booby. ;-)
Cheers em777, yes, I managed to capture the LNG tanker but the light was fading. It took an age for you guys to take her off the berth and turn her around. I was waiting in the top field in a biting NE wind.

Fine shot mattyboy! Did you get the BP LNG tanker?

*story, not soty....

Always a gem of a soty or comment from @MattyBoy...is the bird a petrel or a large gull ?

Thanks for this photo and the little story. The farmer towing sheep and the seagull drone really made my day! :-))

Hey Jim, thanks for that. I left home to catch another vessel leaving, which was then delayed and on the drive up on a section of road that runs parallel to the waterway, I could see this one slowly leaving her berth & then the worst thing happened ! I got caught behind a farmer towing sheep - I was travelling at almost the same speed as the vessel departing which is why I only managed to photograph her rear end !

Love it MattyBoy

Both - my new seagull drone !!

WOW!! An UFO!! Or a seagull???
