Red-billed Queleas "chasing" Elephants away from a waterhole in East Tsavo

Red-billed queleas are small birds but this footage really does show what power there is in numbers. I have stood close to flocks of roosting starlings and watched thousands of knot feeding on the muddy shores of the Wash and the sense of spectacle is amazing. It is hard to explain the sound but they almost create their own weather system as their combined wing beats create a 'wind'. You can sense that the elephants are perplexed by the whole situation.......
