The tragically early death of Lonesome George (1912-2012)
The giant tortoise's demise means his kind are extinct. Michael McCarthy pays tribute and asks which species is next
Michael McCarthy, formerly the Independent’s longstanding Environment Editor, now its Environment Columnist, is one of Britain’s leading writers on the environment and the natural world. He has won a string of awards for his work, including Environment Journalist of the Year (three times) and Specialist Writer of the Year in the British Press Awards in 2001. In 2007 he was awarded the Medal of the RSPB for “Outstanding Services to Conservation,” in 2010 he was awarded the Silver Medal of the Zoological Society of London, and in 2011 the Dilys Breeze Medal of the British Trust for Ornithology. In 2009 McCarthy published Say Goodbye To The Cuckoo (John Murray), a study of Britain’s declining migrant birds.

It may be a curlew or a kakapo. It may be the baiji, or a bat. But no one knows for sure now, what is the rarest creature on the planet.
The title is going begging this week after the death of Lonesome George, a giant tortoise from the Galapagos Islands who was the last remaining member of his sub-species.
George was thought to be about 100 years old, which makes his death tragically premature as giant tortoises are thought to live to about 200.
There are other species hovering around the top of the endangered species list. But none has quite George's distinctive and unchallengeable claim to uniqueness, as the sole remaining member of his type on the planet.
George was from Pinta Island in the Galapagos, and there were no more members of the Pinta sub-species of the giant tortoise to be found anywhere.
Indeed, scientists believed that Chelonoidis nigra abingdoni had become extinct until George was discovered on Pinta in 1972. Subsequently, he became part of the Galapagos National Park tortoise breeding programme and was encouraged to mate with females of a closely related sub-species but never succeeded in reproducing.
However, he did become a tourist symbol of the Galapagos, famed as the Pacific archipelago visited by the young Charles Darwin in 1835 and now receiving 180,000 visitors a year. (Darwin's observations of how similar species differed slightly from island to island – including the tortoises – started his thinking on the origin of species and evolution.)
A dozen giant tortoise sub-species remain on the islands, with about 20,000 animals in total. When Darwin visited, they were plentiful but later in the 19th century, they were hunted for their meat by fishermen and sailors until their population dropped alarmingly. Their population has now recovered – except, of course, for the Pinta sub-species.
National Park officials said George was found dead in his corral by his keeper Fausto Llerena, who had looked after him for 40 years.
So who is to replace him at the pinnacle of the endangered species list? The best candidates are those creatures which may actually have gone extinct, but might be surviving in tiny numbers. In mammal terms that means the baiji – or Yangtze river dolphin of China – which has been driven to the brink, or possibly over it, by the pollution the Yangtse has had to accommodate during China's industrialisation.
In 2006, an expedition failed to find any of the animals, and it was declared extinct, but the following year a baiji-like creature was filmed in the river – so perhaps a tiny number remain.
A similar situation concerns what may be the world's rarest bird, which is probably one of two curlew species – either the eskimo curlew of North and South America, or the slender-billed curlew of Europe, Asia and North Africa.
The eskimo curlew has not been recorded with certainty since 1963 although there have been possible sightings as late as 2006 in Nova Scotia; and while a slender-billed curlew was seen in Northumberland in 1998, there have been no sightings since which have been documented with photographs.
There are many other birds that are down to small numbers, such as the kakapo, the flightless nocturnal parrot of New Zealand, or perhaps the rarest duck, the Madagascar pochard, of which only 60 individuals remain.
The rarest mammals that are definitely still with us include the northern hairy-nosed wombat of Australia (just over 100 remain), the Seychelles sheath-tailed bat (fewer than 100), and the Javan rhinoceros (fewer than 60).
But none exists in such definite and splendid isolation as Lonesome George did, in his solitary Galapagos splendour.
Catch them while you can: dying species
The baiji or Yangtze river dolphin (Lipotes vexillifer), is one of five species of river dolphin – smallish marine mammals that have adapted to living in fresh water. The others are the La Plata river dolphin of southern South America, the Ganges and Indus river dolphins in India and Pakistan, and the pink Amazon river dolphin, or boto, in Brazil.
The eskimo curlew (Numenius borealis) is among eight curlew species in the world. It was – or is – a bird which bred on the Arctic tundra of western Canada and Alaska and then migrated thousands of miles to spend the winter in South America. It was once one of the world's most numerous waders but was killed in huge numbers at the end of the 19th century.
