Rare turtle washes up 4,000 miles from home

One of the world's rarest turtles is beginning to show signs of recovery after washing up on the Welsh coast.

The Kemp's Ridley sea turtle has been named Tally by Anglesey Sea Zoo, where it is being nursed back to health.

On Sunday, Tally was found on Talacre beach, Flintshire, 4,000 miles (6,437 km) away from its usual waters in the Gulf of Mexico.

But how did Tally end up so far from home?

Nick Hartley explains.
