Join our new survey of Nightjars, Woodlarks, Dartford Warblers and a number of other important heathland species in 2025.

The Heathland Birds Survey will survey all the Nightjars, Woodlarks and Dartford Warblers, in all habitats, throughout the UK and Channel Islands. The survey aims to cover all the main occupied sites as well as surrounding suitable habitats where these species may have expanded more recently. It will also record a number of other important heathland bird species.

The previous population estimates made for Woodlark, Nightjar and Dartford Warbler are now almost 20 years old, based on data from surveys undertaken at a time when all three species had undergone a substantial increase in both population size and range. Both Woodlark and Dartford Warbler were at their most northerly recorded UK breeding range extents, while Nightjar was regaining ground in northern England and even into Scotland.
