The spotted hyenas in the Ngorongoro Crater have become one of the world’s best-studied mammal populations. Outstanding are the detailed genetic pedigree that includes virtually all Crater hyenas and the long-term life history data from several thousand individuals. You can contribute to our project by making a donation or reporting sightings of hyenas.
