NanoTags (Coded VHF) for birds and bats

  • Product Type Icon Tag

Monitor all your birds and bats simultaneously with 0.26g coded radio tags.

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.

The NanoTag’s field-proven, energy-efficient design delivers a highly stable signal, while its diminutive size and long operational life allow ornithologists, chiropterologists and even entomologists to collect movement data on tiny species.

  • Product Features

    Coded signals
    Employing Lotek’s unique coded transmitter technology, these tags allow you to track and identify hundreds of individuals on a single frequency. 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 and deactivation
    Eliminates need for magnet removal or attachment during field sessions.

    Long life
    NTQB2s allow you to track for even longer than previous versions with the possibility to track for a year with a sub-gram tag.

    Programmable
    A variety of options available to extend operational life with on/off cycles.

     

  • 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.

    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: Suitably robust to be left in the field for long periods
    SRX800-MD: Appropriate for manual tracking of tags as well as for a logging station
