Area of Science:

  • Ecology
  • Artificial Intelligence
  • Animal Behavior

Background:

  • Bio-logging is crucial for studying wild animals, but high-cost sensors limit device runtime.
  • Current bio-logging methods struggle with limited data collection windows due to power constraints.

Purpose of the Study:

  • To develop an AI-powered system for on-board detection of target behaviors using low-cost sensors.
  • To conserve limited resources on bio-loggers by selectively recording data.

Main Methods:

  • Implementing AI algorithms on video-loggers to process data from low-cost sensors like accelerometers.
  • Testing the AI system on bio-loggers attached to seabirds (gulls and shearwaters).

Main Results:

  • The AI method achieved 15 times the precision in capturing target videos compared to periodic sampling.
  • Demonstrated effective detection of complex behaviors in wild seabirds.

Conclusions:

  • AI integration in bio-loggers enhances efficiency and extends data collection capabilities.
  • This approach can reveal previously unobserved aspects of animal lives, advancing ecological understanding.
