Number of nesting Manx shearwaters almost triples in three years after a project, backed by Prince Charles, sucessfully kills off the rats that eat the birds’ chicks and eggs

A scheme to kill rats on two of the Isles of Scilly, backed by Prince Charles, has led to a resurgence in rare sea birds.

The number of Manx shearwaters has risen to 73 nesting pairs this year, the highest in living memory and almost triple the number of nesting birds just three years ago. The birds appear to be breeding successfully, with 30 chicks spotted on the popular holiday islands. Another species of rare ground-nesting birds, storm petrels, have also returned to the Scillies.
