Turtles are loyal in feeding as well as in breeding

A research team led by the University of Exeter has discovered that, after laying their eggs, sea turtles travel hundreds of miles to feed at exactly the same sites. The research, funded by the Natural Environment Research Council (NERC), shows for the first time that marine turtles appear to be as loyal to specific foraging sites and migratory routes as they are to nesting sites. Published today (25 April) in the journal Proceedings of the Royal Society B: Biological Sciences, the findings strengthen the argument for the protection of key foraging sites of these endangered species.

'The extent to which turtles showed fidelity to specific foraging sites and routes was a surprise,' said Dr Annette Broderick of the University of Exeter. 'Marine turtles migrate hundreds of miles between breeding and foraging grounds, so it is amazing that they are able to return to exactly the same sites via very similar routes. We do not yet know why they return to the same sites, but these findings give us a much better picture of the behaviour of adult turtles at sea, where they spend the majority of their life cycle.'

Scientists have long known that marine turtles return to the same breeding sites each year, but did not know until now that they also revisited foraging sites. Dr Broderick and her team tracked twenty green and loggerhead turtles nesting at two beaches on Cyprus, using satellite transmitters. All females tracked for more than six months remained in the same foraging grounds, moving to deeper water for the winter where they conducted dives of up to a record breaking 10.2 hours. Five females were also tracked when they nested again up to five years later and returned to the same foraging sites.

Green turtles have been observed cropping sea grass gardens to encourage new growth, so there could be a benefit to them returning to foraging grounds. Loggerheads have an omnivorous diet, including molluscs and crustacea, so the benefit to them revisi
