Solar assisted NanoTags
to track your birds for even longer!

Lotek supplies the smallest Avian coded VHF NanoTags available today, enabling researchers to investigate migratory movements of the smallest of birds and bats through the Motus network. On a more local scale, these tags can establish the presence and absence of individual animals at points of interest such as communal roosts, breeding colonies or man-made artefacts.

Our solar tags can extend the life of the energy-efficient NanoTags even longer. They contain a cell, so will work during long periods without sunlight. Imagine getting detections of your migrating small birds year after year.


Solar NanoTags

  • Product Features

    Extra-Long life
    With the solar panel re-fuelling the cell, a small tag has the potential to keep transmitting indefinitely.

    Coded signals
    Employing Lotek’s unique coded transmitter technology, these tags allow you to track and identify hundreds of individuals on a single frequency. Over 24,000 unique combinations possible. This reduces the probability of missing individuals due to listening on a different frequency. Designed for use with Lotek digitally encoded receivers, such as the SRX 800.

    Infrared activation
    Eliminates need for magnet removal or attachment during field sessions.


  • Product Applications

    Great for:

    • Flyway Studies – automated logging of birds or bats flying through area
    • Migration Stopover Ecology – record when your tagged animals are present
    • Colony Nesting Studies – log all parental feeding visits automatically
    • Flight Searches – save time while searching by only listening to one frequency
    • Bat Roost Behaviour – detect Bats leaving and returning to a roost

    Avian NanoTag-series transmitters are ideally suited for studies involving passerines, bats, water birds and other species that require small, long-life transmitters and the ability to detect multiple individuals occupying the same area.

    The most common use of Avian NanoTags is studying migration and stopover ecology using the Motus Wildlife Tracking System, which has led to some exciting discoveries about the timing of migration, the speed birds migrate and the routes they take.

    Other more localised studies include recording presence absence at roosting sites, recording feeding events at seabird colonies and looking at social networks by seeing who is visiting the same site at the same time. There are many other possible studies when you want to know when an animal is at a particular site.

    Contact one of our Telemetry Specialists for more information.

    2. Tags can operate for an indefinite duration when sufficient solar energy can be harvested and the tags are not subjected to excessive wear and tear
    Features and specifications subject to change without notice.

    Technical specifications:
    Operating temperature: 0˚C – +35˚C
    Coded tags require receivers that can decode the signals to tell you which individual has been detected.
    They are best used with our SRX receivers:
    SRX800-D: Designed specifically for extended autonomous datalogging applications
    SRX800-MD: Designed for both mobile and extended autonomous datalogging applications
