Gone, But Not Forgotten: Species We’ve Lost in the Last 10 Years

Mankind has the honour of quite possibly being the most destructive force to ever hit Mother Nature. With 150 to 200 species of life ceasing to exist every 24 hours, a mass extinction is looming, and biodiversity is in crisis.

Periods of extinction are nothing new in the planet’s history, but species extinction in the past 10 years is far greater than anything the world has experienced in the past 65 million years. Humankind’s unsustainable production and consumption are without a doubt the major contributing factor. For the first time since the disappearance of the dinosaurs, humans are driving both animal and plant species to extinction faster than new ones can evolve.

Although we can’t honour them all, here’s a glimpse at just some of the beautiful creatures that we’ve lost forever in the last decade:

West African Black Rhinoceros
Officially declared extinct in 2011, the majestic West African Black Rhino was a victim of rampant poaching. Hunted for its horn, which is believed by some in China and Yemen to possess aphrodisiacal qualities, conservationists searched for signs of its last remaining habitat in Cameroon in 2006, but were unable to find any traces. The West African Black Rhino was one of four subspecies of rhinoceros. The other three remaining subspecies are all critically endangered.

Caribbean Monk Seal
Even though nobody has sighted a Caribbean Monk Seal since 1952, it wasn’t until 2008 that this impressive creature was declared extinct. Hunted extensively for its blubber for use in oil lamps and machinery in the 1700s and 1800s, the Caribbean Monk Seal was an unaggressive and curious animal. Early habitat destruction and human hunting was likely to blame for their demise, as these once abundant seals were regarded as ‘competitors’ by fisherman.

Po’ouli / Black-faced Honeycreeper
Native to Hawaii, the Po’ouli or Black-faced Honeycreeper was only discovered in the 1970s at which point they were already on the decline. Efforts were made to get the remaining birds to breed, but attempts were unsuccessful, and the last one of its kind died in 2004. Changes to Hawaii’s ecosystem caused by non-native species, along with habitat loss and disease, are the main reasons why we have lost this unique bird.

Fast Fact Attack: Endangered Species No. 67 – The California Condor


California condors from mother nature network

“There will be no justice as long as man will stand with a knife or with a gun and destroy those who are weaker than he is”
Isaac Bashevis Singer

Native American tribes see the condor as a symbol of power.  Known to them as the Thunderbird, they believe it creates thunder in the sky by beating its enormous ten foot wings.

In flight, the majestic wings can be seen in all their splendour.  When airborne, the distinctive white patch underneath each wing is highly visible, distinguishing it from other vultures.  These great birds soar as high as fifteen thousand feet across the skies, catching thermals on the way up, rising as the ground below gets hotter.  They can stay up for hours watching, searching for food and other needs.

California condors are vultures.  Like all vultures, they are carrion feeders, not predators. As such, they are a very important part of the ecosystem, acting as  ‘nature’s cleaners’ by recycling dead organic waste.  They pick up all sorts of animal debris that would otherwise be left to rot where it fell.  They come equipped with a very tough immune system which protects then against any harmful bacteria found on decaying animals. They have incredibly keen eyesight, but a poor sense of smell, which is perhaps quite fortunate considering their feeding habits.  Their baldness is one of their many assets.  It allows them to bury into the carcasses they feed on without too much mess.  Meal over, they clean their heads and necks by rubbing them on grass or against rocks or branches.

Condors can travel up to one hundred and fifty miles a day, with a maximum flight speed of fifty-five mph.  These magnificent birds have a wing span of just under ten feet.  Their feathers are essentially black with white patches under the wings.  Their bald heads are white to reddish-purple.  They can reach a height of fifty inches, weigh up to twenty-five pounds and can live up to as much as eighty years, although sixty is more common.

The mating season for the California condor is winter to spring, followed by an incubation period of about fifty-four days.  One chick will hatch, which will receive the parents full attention.  The chick will learn to fly at the age of six months, but may stay with its parents for the next two years.  It will not gain full adult plumage until five or six years of age.

Habitat
Rocky, forested regions permeated with caves, gorges and ledges for nesting.  Open grassland for hunting.
Where
By reintroduction:  Mexico and the United States of America
What they eat
Carrion:  Condors will tuck into most carcasses they find, but prefer the larger ones, such as deer, cattle and sheep.
Threats
Lead poisoning, habitat loss, illegal shootings and human intolerance.
Status: Critically Endangered
The California condor is listed on the  IUCN Red List of Threatened Species  as Critically Endangered.  It is also under the protection of  CITES Appendix I

By 1982, only twenty-two individuals existed.   The species became extinct in the wild in 1987, when the last free-flying condors were taken into captivity to save the species via a breeding program.  At this point, only nine birds remained on the planet.  The captive breeding program was successful, and, in 1991, action was taken to start releasing the birds back into the wild.  By the spring of 2013, there were over four hundred and thirty California condors in existence, either in captivity or free-flying.
The problem of lead poisoning from  ammunition  has been addressed in California. Where, since 2007, only lead-free ammunition is permitted when hunting.  However, you will see from the link below, the LA Times reports a rise in lead poisoning of condors.  Effective or not, no such laws have been passed elsewhere yet, making the problem widespread.
