Death of Nabiré: Only Four Known Living Northern White Rhinoceroses

Formal scientific interest in northern white rhinoceroses dates to 1908, with English bio-geographer, geologist, and naturalist Richard Lydekker’s (July 25, 1849 – April 16, 1915) official taxonomy in 1908. But simultaneous and subsequent amateur, expert, and newbie observations consistently express reservations over in-the-wild sustainability in:

• native, 10,000,000+-year-old distribution ranges within east Central African Republic, northeast Democratic Republic of the Congo, northwest Uganda, and southernmost South Sudan; and
• suspected bio-geographies into Cameroon and Chad.

They furnish the reason for the National Museum of Natural History’s exquisite Lado Enclave region-born specimen collected along the upper Nile River’s west bank during the Smithsonian’s co-sponsored East Africa Expedition of 1909/1910 with twenty-sixth U.S. President Theodore Roosevelt (October 27, 1858 – January 6, 1919). 

The Smithsonian’s Roosevelt specimen indeed gives excellent information regarding the massive physique of one of sub-Saharan Africa’s two endangered, grey-coated, hearing-guided, mud-wallowing, plant-eating, shade-loving, smell-sensitive, two-horned rhinoceros genera, of which:

• the black, hook-lipped Diceros bicornis (two horns) browses bushes and trees for fruit and leaves; and
• the northern and southern square-lipped white Ceratotherium simum cottoni (white flat-nosed horn-beast) and Ceratotherium simum simum graze on grasses.

It additionally is prescient that only one of the expedition’s specimens is displayed since extinction apparently describes the northern white rhinoceros’s status in the wild and reproduction historically is problematic in captivity. Scientists indeed judge live birth impossible because of:

• Fatu’s infertility;
• Najin’s weak hind legs;
• Nola’s age; and
• Sudan’s low-quality sperm. 

Scientists currently know of one option for ensuring northern white rhinoceros-filled futures:

• in-vitro fertilizing eggs harvested from Nabiré’s left ovary with sperm collected from Sudan or frozen from long-dead males; and
• transplanting in Nabiré’s closest living relative, a female southern white rhinoceros.

The procedure nevertheless leads researchers into peril-fraught territory because of:

• laboratories having more rhinoceros sperm than eggs; and
• northern white rhinoceros females optimally ovulating one egg every 30+ days.

Scientific advances and technological breakthroughs additionally must surface since nobody yet has experience or expertise in lab-maturing immature eggs and pioneering the world’s first-ever rhinoceros in vitro fertilization.

Hope need not be lost: Dvůr Králové’s staff intend for Nabiré’s life not to be lived in vain. 

My special thanks to talented artists and photographers/concerned organizations who make their fine images available on the internet.
