At first glance this might appear to be a a blurry cloud above the ocean but it is in fact hundreds of seabirds feeding on fish!

News of the feast has spread fast, and you can see more birds approaching from all directions.

If you zoom out it looks like there’s the trail of a ship which has just moved off the image to the South-west, so it’s likely that this frenzy has been caused by fishermen discarding leftover fish. According to Wikipedia this is how some seabird populations get 70% of their total food intake!
