Community acoustic monitoring
VIREO Initiative is an early-stage, student-led effort building open acoustic datasets that others can use for research, conservation, and education. We use passive acoustic monitoring to understand how environmental sound reflects wildlife and habitat, and how human activity shapes it.
Mission
To build and openly share acoustic datasets that help people understand and protect biodiversity.
About
Healthy habitats have distinctive acoustic signatures. By listening to a place over time, we can learn about the wildlife that lives there and how it responds to change, including change driven by human activity, such as noise.
We deploy small, passive acoustic recorders across parks and preserves, then turn those recordings into open datasets and maps. Everything we learn, we aim to release openly so researchers, students, and land managers can use it too.
We are early. Today this is a small effort with a handful of sites and a growing group of volunteers, not a large organization. We would rather say exactly what we have done than more than we have.
A vireo is a small songbird more often discovered by listening than by looking. We chose the name because listening is at the heart of our work: using sound to understand ecosystems, and open data to make what we find useful to others.
Our first sites are forest preserves and parks in Illinois, where the work began. Recorders are installed with permission from the agencies that manage each site.
Open data
We are preparing our first public dataset for release. When it is available, it will be citable and free to use under an open license, the first of what we hope will grow into a shared, openly available acoustic record.
A short, plain description of what the dataset contains: which sites, what time period, and what form the data takes (for example, derived acoustic measures and maps rather than raw audio).
Our recorders capture whatever sound is present in public spaces, which can include human voices. Before any audio-derived data is released, recordings are processed to remove human speech. For this reason we share derived and filtered products, measures and maps computed from the audio, rather than raw recordings.
Protecting the privacy of people captured incidentally in public recordings is a core part of how we prepare data for release.
Research & use
Open acoustic data can support many kinds of work, including ecological research, conservation planning, and classroom learning. Our own first use has been research: a method that turns classified environmental sound into maps of where noise may make habitat harder for birds to use.
We hope the data outlives any single study. The more hands it reaches, including researchers, students, and land managers, the more useful it becomes.
Get involved
Expanding to new sites takes hands in the field and more recorders. If any of the following fits you, we would like to hear from you.
Over time, we hope to grow into a community of volunteers, researchers, educators, and conservation partners building openly available acoustic data that helps us understand changing ecosystems. For now, we are taking the first steps toward that.
