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 upon thorns or barbed wire for facilitated consumption. The numbers of Loggerhead shrike have significantly decreased in recent years, especially in Midwestern, New England and Mid-Atlantic areas. In 1760 the French zoologist Mathurin Jacques Brisson included a description of the loggerhead shrike in his "Ornithologie" based on a specimen collected in Louisiana in the Unites States. He used the French name "La pie-griesche de la Louisiane" and the Latin "Lanius ludovicianus". Although Brisson coined Latin names, these do not usually conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. When in 1766 the
