Leatherback sea turtle predators once they mature; they are most vulnerable to predation in their early life stages. Birds, small mammals, and other opportunists dig up the nests of turtles and consume eggs. Shorebirds and crustaceans prey on the hatchings scrambling for the sea. Once they enter the water, they become prey to predatory fish and cephalopods. Leatherbacks have slightly fewer human-related threats than other sea turtle species. Their flesh contains too much oil and fat to be considered palatable, reducing the demand. However, human activity still endangers leatherback turtles in direct and indirect ways. Directly, a few are caught for their meat
Loggerhead shrike these birds gravitate towards areas of shorter vegetation. Loggerhead shrikes have been repeatedly observed killing prey larger than themselves by spearing the neck or head of the animal and twisting. The speed at which this occurs causes a whiplash injury to the animal. The neck strength of the shrikes compensates, making their talon weakness inconsequential.

They primarily eat insects, but also consume arachnids, reptiles, amphibians, rodents, bats and small birds. The size of prey ranges from 0.001 g insects to 25 g
