Red Kite -- The Red Kite was saved from national extinction by one of the world's longest running protection programmes, and has now been successfully re-introduced to England and Scotland. I like the shift from orange to green.
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."
