Listening deviceThis project aims to establish an "acoustic observatory" for ecological and environmental research. By teaming up acoustic recorders with automated call recognition validated using crowd-sourcing, the researchers intend to create an online storehouse of natural sounds from a wide range of localities.  While eventually extending to all natural sounds (including frogs, insects, bats and various other mammals) this initial proof-of concept project uses birds, collecting acoustic data and using machine learning and volunteer birders to identify calls to species.  Once catalogued, these data will then be accessible to researchers and the general public, representing an alternative source of data for researchers to address a number of ecological questions without needing to undertake dedicated fieldwork.

The research team includes post-doctoral researcher Dr Maggie Watson and PhD students Jason Wimmer and Jessie Cappadonna. Stations have been installed along four creek-lines in Sturt National Park, where Prof Watson has been surveying birds for the last 13 years.

This project has led to a successful ARC Linkage Infrastructure, Equipment and Facilities (LIEF) grant - Acoustic Observatory: a network to monitor biodiversity across Australia. (2017-2020) ARC LIEF project ($900,000) led by Queensland University of Technology with ILWS team members Watson, D., Luck, G. & Nimmo, D.,  - which is being used to purchase and site 350  acoustic recorders around Australia.


The outcomes this project include:

  • New approaches to physical/virtual engagement in human-computer interaction
  • New approaches to analysing big data
  • A new validated ecological monitoring technique and concepts for sustainable knowledge generation communities.
