Watering hole

Ok so this may not look like you normal watering hole (pub or lake on the Serengeti) but sat next to the pool this evening a bird kept swooping down from the tree and drinking from the pool in mid flight. Something I have not see before. At 1st I did think I had spent to long out in the sun and i was seeing things, but then it kept doing it. See if you can spot the bird :)
