A project to survey and understand as much as we can about the European Nightjar (Caprimulgus europaeus) in the Forest of Dean, using a combination of observation, remote audio recording, field recordings, bio-acoustic analysis, ringing, telemetry, DNA sampling, photography and trail cameras. The project began back in 2002 but has grown both in its scope and methodology since that time.

This website collates some of the media that results from the project. Complete, accurate records and breeding data are submitted to the BTO and County Bird Recorder annually, as well as shared with the relevant land owner/manager. The project is funded by a combination of grants from Gloucestershire Naturalists’ Society, Forestry England, a lottery funded local conservation project and personal funds.
