The marine bird is threatened by high tides and beachgoers, but volunteers give a helping hand.

Hidden in the scrapes, this little tern chick is camouflaged - and vulnerable - on a Norfolk beach.

But it is surrounded by a record 700 other ground nests due to a project set up to protect the threatened species 40 years ago.

With the help of local volunteers and wardens, who monitor breeding sites 24 hours a day, the future of the little tern is looking much brighter than it did back in 1986.
