A 20-year study of the dingo's diet was conducted across Australia by the federal and state governments. These examined a total of 13,000 stomach contents and fecal samples. For the fecal samples, determining the matching tracks of foxes and feral cats was possible without including these samples in the study, but in distinguishing between the tracks left by dingoes and those of dingo hybrids or feral dogs was impossible.[ The study found that these canines prey on 177 species represented by
- 72.3% mammals (71 species),
- 18.8% birds (53 species),
- 3.3% vegetation (seeds),
- 1.8% reptiles (23 species), and
- 3.8% insects, fish, crabs, and frogs (28 species).
