Birds of prey are birds that hunt for food primarily via flight, using their keen senses, especially vision. They are defined as birds that primarily hunt vertebrates, including other birds. Their talons and beaks tend to be relatively large, powerful and adapted for tearing flesh. In most cases, the females are considerably larger than the males. The term "raptor" is derived from the Latin word rapere (meaning to seize or take by force) and may refer informally to all birds of prey, or specifically to the diurnal group. Because of their predatory lifestyle, often at the top of the food chain, they face distinct conservation concerns.
Off topic but what was the latest Doctor Who episode like?....I switched it off soon as I saw the Statue of liberty behind that building only because those angels can't move if your looking at them and I reckon there would have been a fair number of people looking at the Statue of liberty even if it was the middle of the night as its kind of hard to miss something like that walking through the streets.
