Loggerhead sea turtle Greek coast, the coastlines of Cyprus and Turkey are also common nesting sites. One record of this turtle was made in Ireland when a specimen washed ashore on Ballyhealy Beach in Co. Wexford. Loggerhead sea turtles spend most of their lives in the open ocean and in shallow coastal waters. They rarely come ashore besides the females' brief visits to construct nests and deposit eggs. Hatchling loggerhead turtles live in floating mats of "Sargassum" algae. Adults and juveniles live along the continental shelf as well as in shallow coastal estuaries. In the northwestern Atlantic Ocean, age plays a factor in
Loggerhead shrike length, tail length, and colour. "L. l. migrans" have a paler forehead than the top of the head. According to Mundy et al.’s 1997 study, there is a substantial genetic difference between the island subspecies "L. l. mearnsi" and the mainland subspecies "L. l. gambeli" due to a gene flow barrier between the two species. The loggerhead shrike is a medium-sized passerine. "Loggerhead" refers to the relatively large size of the head as compared to the rest of the body. It measures approximately 9 inches from bill to tail. The wing and tail length is about 3.82 and 3.87 inches
