What eats birds?

I really don't wanna say this but I have to: almost every single animal on planet earth eats birds! From cats to pigs, these animals are way at the bottom of the food chain! but I know a few (a few, not a lot) animals that don't eat birds like elephants for example. They don't even eat birds. But I think birds will forever be at the bottom of the food chain right next to butterflies. Also, many humans eat thousands of birds a year.
