Amur Tiger

This is one of the adult Amur Tigers (endangered) at the Calgary Zoo, photographed on 16 April 2013. Can't remember for sure, but this may be the mother of the three cubs that were born in April 2012.

"Siberian (or Amur) tigers are the world's largest cats. They live primarily in eastern Russia's birch forests, though some exist in China and North Korea. There are an estimated 400 to 500 Siberian tigers living in the wild, and recent studies suggest that these numbers are stable. Though their northern climate is far harsher than those of other tigers, these animals have some advantages. Northern forests offer the lowest human density of any tiger habitat, and the most complete ecosystem. The vast woodlands also allow tigers far more room to roam, as Russia's timber industry is currently less extensive than that of many other countries."

Later note added on 14 June 2012:
Tigers that used to be known as Siberian Tigers are now known as Amur Tigers. The name change is because their range now only includes the Amur Valley in Eastern Siberia.
