Throughout North America, bats are the primary predators of nocturnal flying insects, providing millions of dollars in pest control services annually. Bats occur in nearly every habitat on the continent, from high elevation alpine forests to deserts and neighborhoods within our largest cities.
Because bats fly in the dark of night, it is challenging to understand their behaviors and monitor their population status.
To get around this challenge, biologists use bat detectors to better understand bat ecology. These devices record the echolocation calls of nearby bats, and combined with specialized software and expert knowledge, biologists can often identify bat species from these detections. Biologists deploy these detectors for one or more nights at locations across the continent throughout the year, and may monitor presence or activity of various bat species each night.
This application is a companion to the Bat Acoustic Monitoring Portal (BatAMP).
BatAMP provides a central platform where biologists can upload their detection data in order to better understand the distribution, seasonal movement patterns, and population status of bats across North America. These data are then compiled for visualization within this tool.

This application enables you to explore bat monitoring data for 37 species across North America, allowing you to explore seasonal trends in species detections and explore bat activity for a particular location.
Explore detailed monitoring data for each of the species included in this application. Each species has a dedicated visualization page that enables you to:
Explore occurrence data aggregated across all species within this application. This allows you to:
This application leverages the combined efforts of 199 contributors and would not be possible without their hard work. Together, these contributors have collected over 30,422,141 bat detections on 245,773 nights using 3,631 detectors, and they have collected 6,367,242 detections of at least 37 species.
