I think I mentioned previously that the terns on Farne were surprisingly small once you got up close and personal. This photo perhaps helps judge their size a little bit and demonstrates how many of them were nesting directly on the ground amidst the long grasses. That meant you often couldnt' see the chicks at all, but made for good photos as the parents flapped and hovered just above.

So far all my pictures were Arctic terns (or maybe Common – the differences are minor) but this is a Sandwich tern – markedly different without the red accents, and just a yellow tip to the bill. This ones demonstrating that it eats Sand eels, the same as the puffins.
