Many billion songbirds migrate every year between continents. Similarly, many bat species and countless large insects migrate long distances, potentially also between continents. Scientists are so far unable to follow individual small animal during their long-distance migrations. Knowledge about individual decisions is essential for an ecological and evolutionary understanding of dispersal and migration.

We propose a global tracking system for small animals that will immeasurably contribute to progress in experimental field biology and biological conservation. Tracking small animals globally will also help us understand how ecosystem services by small animals (many billion $s per year) emerge and can be preserved. Once we can follow small animals we will also be armed with knowledge against biological invasions and the spread of pandemic diseases that are carried by small animals (bats, birds, insects).
