Our nomination relates to the research and development of bioacoustics survey skills for the monitoring of European nightjar, a species of bird often perceived as being in conflict with wind farm developments and operations. Nightjars are widespread in Wales and can be a considerable constraint to development as they receive special legal protection.
Bioacoustics and the nightjar
Traditional survey methods used to establish the presence of nightjars, a bird both elusive and cryptic in behaviour, are expensive and can necessitate walked transect surveys, tape luring surveys and radio tracking to map their distribution and nest sites.
During 2013 and 2014, we carried out research into the use of bioacoustics survey methods as an alternative to conventional methods.

Andrew Baker, Managing Director of Baker Consultants, says: “At their basic level, bioacoustics surveys involve placing recording devices out in the field, often for extended periods, and recording animal sounds. This has many advantages over conventional surveys techniques, as a large amount of data can be gathered over an extended period of time as recording devices are left unattended for up to three months. Such data is critical, making it possible to establish whether records of nightjar are simply those passing through or those with established territories on the site.This can provide crucial information regarding whether a development gains approval. Furthermore, the costs of bioacoustics surveys are much lower than conventional methods”.
Baker Consultants also funded research by Dr Mieke Zwart as part of a joint project led by Dr Mark Whittingham of Newcastle University. The research proved that the use of bioacoustics was much more effective than established methods and was published as a peer-reviewed paper. This established the value of bioacoustics in nightjar surveying and paved the way for wider use of this cost-effective survey technique. There is also considerable potential for further development of this technique to allow a more detailed understanding of the use of a site by nightjar and other important species.
The Wales Green Energy Awards are in their third year, and organised by RenewableUK Cymru to celebrate the success and achievements of the green energy industry in Wales. The award winners will be announced on Friday 6 November in Cardiff.
David Clubb, Director of RenewableUK Cymru, said: “We are always delighted by the quality of submissions for the Wales Green Energy Awards, and this year is no exception. Each of the shortlisted individuals or organisations should feel extremely proud of what they have achieved over the last 12 months, often in the face of challenging political and policy decisions.”
Baker Consultants and Wales
Baker Consultants has been providing ecological services to projects throughout Wales for a number of years and this year we consolidated our presence with an office in Swansea, following increased demand in the region and growth in the renewables sector.
