Tracking global songbird migration from space

The Global Enigma

  • Billions of songbirds migrate twice every year between continents
  • Songbirds have enormous economic and ecological importance
  • Songbirds disappear during migration for unknown causes; many species show negative populations trends
  • Detailed migration routes are unknown
  • Conventional tracking methods are insufficient

 

 

Important migration routes of small birds

The Solution: radio-tracking songbirds from space

  • Songbirds will cary long-lasting radio-transmitters on their backs (1-3 grams)
  • A radio receiver in lower orbit, for example, on the International Space Station (ISS) will detect the birds' radio signals
  • The ISS criss-crosses the globe and covers continental North America 7 times per day for ~ 8 minutes each
  • Signals can be located within a ~120 kilometer circle: this is sufficient for intercontinental migration
  • Scientists across the world will be able to follow bird (small animal) migration
  • This project will solve a riddle as old as humankind: where do our birds go?

 



The Significance

  • Conservation: establishment of stop-over reserves and migration corridors
  • Basic Science: solving orientation capacities of birds in the wild; potential to study dispersal of birds: "Where do the kids settle next year?"
  • Education: students and citizens will follow songbird migration on the www
  • Understanding Among Nations: songbirds as ambassadors for peace
