Motus Wildlife Tracking System

The Motus wildlife tracking system is a collaborative research network using coordinated, automated radio telemetry arrays to study movements of small animals. Receivers in Motus towers automatically record the radio signals from radio-tagged wildlife present nearby. Thousands of researchers use the network of 1,250+ Motus towers to study species from bats to albatrosses. Cedar Island NWR hosts a Motus tower, which will record signals from any and all Motus-tagged wildlife nearby, contributing to hundreds of ongoing research projects. More information can be found at https://motus.org/.
