Nightingale

Anglian Water has been working with the British Trust for Ornithology and the Bedfordshire, Cambridgeshire and Northamptonshire Wildlife Trust to research why Nightingales have declined by a staggering 90% in the UK over the last 40 years.

In 2012 the project tracked 20 male Nightingales, 3 were from Grafham Water. By fitting a small geo-locator to the back of the birds it’s hoped we'll gain a better insight to the route that they take and where they spend the winter months.

The surveys at Grafham are carried from mid-April to the end of May between midnight and 4am to first work out from where the male Nightingales are singing.

The Nightingales are then caught under licence in fine mist nets, a ring with a unique number is fitted to a leg and various measurements are taken before the birds are then released.
