Avian Studies of Motus, a Global Wildlife Tracking System
Feature-in-Progress
Guest Editors: Mark Hauber, Dave Shutler
The Motus Wildlife Tracking System (https://motus.org) is a collaborative global research network that uses automated radio telemetry to track the movements and behavior of birds, bats, and insects. This technology has revolutionized the tracking of small-bodied birds that are unable to carry heavier tags previously required for long-distance or remote tracking (e.g., via satellites). Studies utilizing automated radio telemetry and the Motus network, including those in this collection, have addressed a broad range of avian topics, including migratory connectivity, migratory timing, stopover use and duration, non-migratory movements, habitat use and selection, and weather conditions associated with migratory departures and movements. Several articles investigate potential effects of tags on bird behavior and productivity and provide guidance on tag and antenna specifications for specific study questions, which is critical to the success of future ethical research.
Motus is composed of more than 2500 receiving stations that are supported by hundreds of collaborating groups across 34 countries. Researchers have tagged more than 67,000 animals of more than 400 species that are tracked by the system, supporting more than 250 publications. Motus is one of the largest collaborative research infrastructure projects and houses the largest open database on animal movement data in the world. Motus is a powerful, accessible tool for connecting youth to real research, building technical skills, and generating data that can information conservation locally and globally.
