Not much of ornithological interest apart from a few Common Gulls, but a large bull [I believe] Seal was just off the barrage rocks just beyond the sluices. I’ve posted a vid clip on my FB wall. Can’t insert video clips here but here’s a link to the clip on YouTube: https://youtu.be/V7g534bnx40

Hi John a male Atlantic Grey Seal very nice. Cheers Mike
Cheers Mike – yep, confirmed on Facebook as Atlantic Grey – thought it as due to the ‘roman nose’ and no peaked forehead. Second time I’ve seen one there.
