Birds of prey eat other birds, as do some corvids (crows), for instance Eurasian Magpies eat the eggs and chicks of small songbirds.
The Mockingbird eats fruit, insects, spiders, and small animals like lizards and snakes.
The white shark can eat a cormorant or an albatross that is in the water, as well as the snuff can do it even with gulls. Both are very voracious fishes.
Just about all of it, depending on species. Fruits and seeds are particularly popular.
