Video: Kids keep whistling language alive

Children on a Spanish island are keeping an ancient whistling language alive.

Silbo gomero is a whistled version of Spanish which can be heard up to two miles away!

Before phones and roads were invented, whistling was a way the islanders could communicate through the valleys of the Canary Island of La Gomera.

But the whistling language is still going strong, thanks to lessons at a local school.
