Bird Tracking and Biologging Devices for Avian Research

Bird tracking devices help researchers investigate migration, movement ecology, behaviour, habitat use and social interactions across a wide range of avian species. Effective bird GPS tracking, however, requires more than selecting a small logger. Body size, flight behaviour, habitat, attachment method, deployment duration and power availability can all influence the final configuration. At TechnoSmArt, we develop customizable animal tracking and bird biologging systems for species ranging from small passerines to raptors, waterfowl, seabirds and diving birds.Available technologies include GPS tracking, tri-axial acceleration, proximity logging, magnetometry, temperature and pressure sensing, light, CO₂ and wet/dry sensors.

Depending on device size and power budget, data-retrieval options can include archival storage, UHF remote download, LTE connectivity and Iridium satellite communication. Selected systems can also use solar charging.

Attachment is a key part of every avian tracking project. Our devices can use TESA tape attachments for seabirds, backpack harnesses, leg-loop harnesses, glue-on systems and other species-specific attachment methods.

Device shape, housing, battery, antenna and attachment system can all be adapted to the target species and field protocol.

For weight-sensitive applications, our smallest configurations can start from approximately 0.9 g while combining GPS, tri-axial acceleration, proximity functions, UHF communication and solar charging. TechnoSmArt systems can support studies on seabirds, shorebirds, waders, raptors, waterfowl, passerines, gulls and terns, pelagic birds, colonial waterbirds, herons, egrets, owls, gamebirds and many other avian taxa.

Choose the Right Device

Choosing the right bird tracking device requires a balance between body mass, biological objectives and field conditions.

Researchers should consider:

  • target species
  • device mass
  • attachment method
  • habitat
  • GPS exposure
  • deployment duration
  • required sensors
  • power budget
  • recovery probability
  • data-retrieval method

For very small birds, device mass and power consumption may represent the main constraints. Seabird studies may instead require waterproof housings, pressure sensors and wet/dry sensing. Long-range communication through LTE or Iridium generally requires more power and antenna space than ultra-light UHF systems and is therefore more suitable for configurations where the available size and energy budget permit it.

Bird Tracking and Biologging Technologies

Small birds

Small bird GPS tracking requires extremely lightweight electronics, efficient power management and careful optimization of recording schedules.

Zero Trek represents our most compact integrated solution and can start from approximately 0.9 g. Configurations can combine GPS, tri-axial acceleration, proximity logging, UHF remote communication and solar charging.

Other lightweight solutions include archival and UHF-enabled GPS systems for birds that regularly return to colonies, nests or roosts.

GPS Tracking & Behaviour

Combining GPS and tri-axial acceleration allows researchers to investigate both movement and behaviour during the same deployment.

Applications include:

  • migration
  • flight behaviour
  • foraging
  • stopover ecology
  • habitat use
  • activity patterns

Additional sensor options can include magnetometers, pressure, temperature, light, CO₂, wet/dry sensors and proximity logging.

Seabirds & Diving Birds

Tracking seabirds presents specific technical challenges. Devices must often tolerate salt water, repeated immersion and diving pressure while maintaining reliable sensor acquisition.

Multi-sensor configurations can combine:

  • GPS
  • acceleration
  • pressure/depth
  • temperature
  • light
  • wet/dry sensing

These systems can support studies of foraging trips, dive profiles, marine habitat use, commuting behaviour and transitions between flight, resting and water activity. For many seabird projects, TESA tape provides a practical attachment method. However, the final attachment configuration depends on species morphology, plumage, deployment duration and study objectives.

Behaviour Biologing

Bird biologging can provide information that GPS positions alone cannot reveal.

High-resolution acceleration and magnetometry can support:

  • behavioural classification
  • activity budgets
  • flight analysis
  • orientation studies
  • fine-scale movement analysis

Optional light sensing can also provide information on environmental light conditions or support geolocation-related applications. Selected configurations may integrate CO₂ sensing for specific ecological or experimental research questions.

Remote UHF data download

Depending on species, device size and power availability, bird tracking systems can use different data-access strategies:

  • archival storage
  • UHF remote download
  • LTE cellular communication
  • Iridium satellite communication

UHF systems are especially useful around breeding colonies, nests and roosts.

LTE can support remote data transmission where cellular coverage is available. Iridium satellite connectivity can provide data communication in remote areas without cellular coverage, provided the device configuration can support the additional antenna and power requirements.

Proximity logging

Proximity logging allows researchers to investigate interactions between tagged birds.

Applications include:

  • social networks
  • pair bonds
  • parent–offspring interactions
  • colony structure
  • group associations
  • contact rates

Proximity functions can also be integrated into selected GPS tracking configurations

Custom Bird Tracking and Biologging Configurations

Species-specific customization is central to bird tracking.

TechnoSmArt can customize:

  • batteries
  • sensors
  • housings
  • antennas
  • GPS schedules
  • UHF communication
  • LTE connectivity
  • Iridium satellite communication
  • solar charging
  • attachment systems

Attachment options include:

  • TESA tape
  • backpack harnesses
  • leg-loop harnesses
  • glue-on attachments
  • customized housings
  • species-specific mounting systems

Researchers can select combinations of GPS, acceleration, proximity, magnetometry, pressure, temperature, light, CO₂ and wet/dry sensing.

FAQ

What’s the lightest GPS device suitable for small passerines?

Gipsy 6 is the lightest GPS logger in our current range, with configurations starting from approximately 1.5 g. Suitability depends on species, body mass, attachment method and deployment duration.

Can I get both GPS and accelerometer data from the same tag?

Yes — the Axy-Trek family includes several devices combining GPS with tri-axial acceleration, including Axy-Trek Mini, Axy-Trek Remote, Axy-Trek Marine and Axy-Trek Marine HD.

How do I track birds that return regularly to a colony without recapturing them?

Remote UHF devices such as Gipsy Remote or Axy-Trek Remote allowing data to be retrieved without recapturing the bird.

Which devices are best for studying diving or seabird behaviour?

Axy-Trek Marine and Axy-Trek Marine HD combine GPS, accelerometer and pressure/temperature sensors, allowing researchers to link horizontal movement with dive profiles and depth.

Do I need GPS to study bird behaviour, or is an accelerometer enough?

For studies focused on behavioural classification without location data, an accelerometer biologger such as Axy 5 S or Axy 5 XS may be sufficient. These devices avoid the additional power requirements of GPS and can provide high-resolution acceleration, magnetometer and temperature data.
