Feature on bioacoustics monitoring of bird populations to save declining species

Baker Consultants’ Technical Director Carlos Abrahams, has been featured in an insightful piece for the most recent edition of Bird Watching magazine, outlining for readers how bioacoustics has changed the way ecologists and bird watchers alike can record and monitor bird populations less invasively and with greater accuracy.

Carlos has been researching the use of audio recorders in monitoring bird populations for many years, and  two recent peer reviewed studies demonstrated how bioacoustics could be used to effectively monitor and survey capercaillies, an ordinarily elusive bird, sensitive to disturbance of its habitat.

This conservation-focused article in Bird Watching magazine demonstrates the expertise of Carlos and his industry-leading work in bioacoustics and soundscapes in relation to the protection of declining species. These methods are being increasingly used by ecologists as they complement existing techniques and can cover other species at the same time as bird calls are monitored. Soundscape ecology assesses the acoustic richness of a habitat in its entirety to assess overall levels of biodiversity in an area, so the technique offers scope beyond birds alone.

In recent months, Carlos has led several webinars and sessions on bioacoustics, sharing his knowledge with his peers and students.  Bioacoustics monitoring has become an important feature of our conservation work at Baker Consultants, where work in this area has led to a shortlisting for a CIEEM award for Best Practice Innovation.
