Swallow-tailed Gull

The Swallow-tailed Gull is near-endemic to the Galapagos Islands, where it has over fifty colonies spread over the entire archipelago.

It is the world's only night-feeding gull, and its chick is the only gull chick with so much white, perhaps so that the returning parents can find them more easily.

There is only one egg laid at a time: this one had apparently been abandoned beside the trail, but 'just in case' I just shot it very quickly and moved on.
