About this course
By the end of this 5-day practical course, attendees will have the capacity to set up and deploy recording devices, download acoustic data, how to analyse this data and report the results.
Bioacoustic methods are becoming increasingly recognised as a valuable approach for ecological surveying. Bioacoustics can be used to effectively replace some current techniques whilst increasing the quality of the data collected or can be used in unison to compliment them. They are particularly useful for developing long-term, permanent datasets that can be independently reviewed, particularly for rare species with low detectability, or when working in difficult environments.
The course will provide a practical introduction to bioacoustics methods, with a mix of lectures and practical workshops, and some optional fieldwork. It will start with a basic introduction to sound and recording theory, before developing hands-on skills in setting-up and deploying a range of acoustic and ultrasonic audio recorders. Workshops will then cover the download and analysis of audio data, mainly using Kaleidoscope Pro and Audacity software. The processed audio data will then be analysed and presented using R, the free software environment for statistical computing and graphics (http://www.r-project.org/).
Example data sets will mostly cover applications for bat and bird surveys, as well as the use of Acoustic Indices as biodiversity metrics. If you are working in different areas of ecology using bioacoustics please feel free to contact email@example.com so we can advise if the learning outcomes are transferable to your field of research.
Duration – Approx. 21 hours
ECT’s – Equal to 1.5 ECT’s
Language – English
Assumed quantitative knowledge
Assumed computer background
Equipment and software requirements
A laptop computer with a working version of R or RStudio is required. R and RStudio are both available as free and open source software for PCs, Macs, and Linux computers. R may be downloaded by following the links here https://www.r-project.org/. RStudio may be downloaded by following the links here: https://www.rstudio.com/.
All the R packages that we will use in this course will be possible to download and install during the workshop itself as and when they are needed, and a full list of required packages will be made available to all attendees prior to the course.
A working webcam is desirable for enhanced interactivity during the live sessions, we encourage attendees to keep their cameras on during live zoom sessions.
Although not strictly required, using a large monitor or preferably even a second monitor will improve he learning experience

Teaches – Bioacoustics for ecologists: Hardware, Survey design and Data analysis (BIAC)
Carlos has been working in the practical fields of ecology and nature conservation for over 25 years. Starting his career in nature reserve and countryside management, he has been an ecological consultant since 2001. Alongside managing a busy consultancy, undertaking Environmental Impact Assessments for a range of clients, he is also a part-time lecturer at Nottingham Trent University on the BSc Environmental Biology. Carlos has previously published research on wetland vegetation/management and amphibian habitat selection. However, after many years of using static and handheld detectors for bat surveys, he is currently engaged in studying the potential of bioacoustic methods for investigating bird populations, especially for rare and declining species such as capercaillie and nightjar.
