most birds of prey, such as Hawks, Owls and red kites...
All owls are raptors, or birds of prey. Which is to say they seize prey in their talons and kill it off with the beak usually. Even small owls like Burrowing or Flammulated owls, which eat insects largely, catch them this way. This is in contrast to a swallow or egret, which just use their mouth/beak, and don't have lethal talons.
