Leatherback sea turtle remain generally unassessed and unevaluated. Recent estimates of global nesting populations are that 26,000 to 43,000 females nest annually, which is a dramatic decline from the 115,000 estimated in 1980. The leatherback turtle population in the Atlantic Ocean ranges across the entire region. They range as far north as the North Sea and to the Cape of Good Hope in the south. Unlike other sea turtles, leatherback feeding areas are in colder waters, where an abundance of their jellyfish prey is found, which broadens their range. However, only a few beaches on both sides of the Atlantic provide nesting sites.
Loggerhead shrike The shrike may also use the thorn to fasten and store its food to return to at a later time. The motion of impalement appears to be instinctive, as parent shrikes do not demonstrate the behavior to their nestlings. However, a young shrike must experience impaling prey upon an actual projection during a critical developmental period; otherwise, it will not learn to use the instinctive impaling action upon an actual projection. Kleptoparasitism has also been observed in nature, in which the shrike chased down another bird and stole its recently-caught prey. Loggerhead shrikes are monogamous birds, and begin breeding during
