Article Summary

  • The presence of an endangered Australian bird species, the Gouldian finches (Erythrura gouldiae), was detected by trace DNA from a frequented watering hole.
  • It has been established that large animal and plants can leave enough trace DNA in their environment to be able to track their presence in a given location.
  • Water bodies are especially good collection sites for environmental DNA (eDNA) since they are often visited by even the most elusive or reclusive species.
