Workers and volunteers at a Wildlife Trust said they were overjoyed after discovering baby beavers had been born at a nature reserve for the first time in more than 400 years.

The new arrivals were spotted at the Nene Wetlands nature reserve, part of Rushden Lakes, in Northamptonshire.

Volunteer Jeannette Smith said after noticing mother Boudica had put on weight, everyone “kept their fingers” crossed that the babies, known as kits, would appear.
