What eats the bird called bee eater?

there are a variety of predators for this bird like other birds called the peregrine falcon, the sparrow hawk and by some land cats but not many predators can consume them or at least catch them as they spend most of their lives eating bees , hornets , wasps ,etc in mid air making it awkward for the predator to consume them, so there is no real predator just for the bee eater, making them almost predator free.
