DailyMail.co.uk (excerpts):  Conservationists have warned that Rudolph's reindeer friends are under threat, as the world's largest herd has gone into decline - and could be wiped out within a few years.  More than 90% of the George River population, which roams northern Canada, has vanished in the past two decades.  Numbers have fallen by 24,000 in the last year alone.  Experts say the reason for the drop is not clear.

Commentary:  More animals have gone extinct in the last decade, than during any other time in modern history.  The Word of God says, "The land will mourn and everyone that dwells in it will languish, with the beasts of the field and the fowls of heaven, yes, the fishes of the sea will also be taken away" Hosea 4:3.   I have included a list of animal extinctions in recent years and brief summary for each species below:

Pyrenean Ibex:  The last natural Pyrenean Ibex, a female named Celia, was found dead on January 6, 2000, killed by a falling tree.  Although her cause of death is known, the reason for the extinction of the subspecies as a whole is a mystery. 
 
Po'ouli Bird:  By 1997, only three birds were known to exist in a Hawaiian reserve.  On September 9, 2004, one of the remaining of three birds, a male, was captured and taken to the Maui Bird Conservation Center in Olinda, in an attempt to breed the bird in captivity.  However, biologists could not find a mate for the male before it died on November 26, 2004. Since 2004, extensive surveys have failed to locate a bird of this species.  

 
Baiji River Dolphin:  The Baiji was a fresh water dolphin found only in the Yangtze River in China. The last known living Baiji was "Qi Qi" which died in 2002.  


Liverpool Pigeon:  The reasons for its extinction are unknown.  Birdlife International added the Liverpool Pigeon to the list of extinct bird species in 2008.  

 
Alaotra Grebe:  The Alaotra Grebe was a grebe endemic to the Lake Alaotra and surrounding lakes in Madagascar.  The species was declared extinct in 2010.

 
Eastern Cougar:  A 1998 study for Canada's National Committee on the Status of Endangered Wildlife in Canada concluded that "there was no objective evidence for the continuous presence of cougars since the last century anywhere in eastern Canada or the eastern United States outside of Florida.  In 1999, the Canadian Geographic reported that for the previous half-century, a debate over whether or not Canada's eastern woods host a cougar species all its own has raged.  Now the answer appears to be "no."  Experts say past sightings were cases of mistaken identification.  


Western Black Rhinoceros:  It was once widespread in the savanna of central-west Africa, but its numbers declined due to poaching.  The Western Black Rhinoceros resided primarily in Cameroon, but recent surveys have failed to locate any and in 2011, it was declared extinct by the Internal Union for Conservation of Nature (IUCN).
