Thousands of starlings surround a lone bird of prey which had swooped down to pick off a straggler. "Starlings have a very particular way of defending themselves from their predators like falcons and harriers. They form a large tightly packed flock and mob their enemy, scaring it off, frequently expanding and contracting and changing shape."
Two goldfinches have a mid-air fight after struggling to get enough space on a bird feeder in a British back garden. Photographer Laurie Campbell snapped away from a hide in his garden for 30 hours to get a picture he was happy with. Laurie, from Berwick-on-Tweed, Northumberland, said: "It can take weeks for the goldfinches to find this bait but once they do, they are hooked."
