In an example of reverse evolution, great frigates have lost the ability to water proof their feathers and are thereby restricted in their hunting ability. They acquire food by using their hooked bills to snatch prey from the water, in addition to harassing other birds and robbing them of their catch (known as kleptoparasitism). If they were to land on the water, they most likely would be unable to take-off again. Fregatidae, Great Frigate Birds, Galapagos Islands.
