Overview
- Nasor, a five-year-old male moved from Rotterdam in December, was officially unveiled in Hannover as the new breeding bull for the eastern black rhino.
- The exchange sent former Hannover male Kito to Rotterdam under the European Endangered Species Programme to reduce inbreeding across participating zoos.
- Keepers report classic bull behavior from Nasor and clear interest in the cow Maisha, with introductions limited to staged, indirect contact for now.
- The zoo plans a potential first meeting in spring if biologically appropriate, and any successful mating would be followed by an estimated 15-month gestation.
- Hannover’s push supports a subspecies with about 500 individuals in the wild, and the EEP has previously aided reintroductions such as five rhinos sent to a Rwandan national park in 2019.
