The most critically endangered species on our list of the ten most critically endangered animals is the ivory-billed woodpecker, which lives—or lived—in the Southeastern part of the US as well as Cuba. This huge woodpecker was considered extinct until 2004, when a handful of tantalizing reports of sightings in Arkansas and Florida began to trickle in. However, definitive proof for the ivory-bill’s continued existence has remained elusive, and if a population does exist, it is likely to be tiny and extremely vulnerable. The ivory-billed woodpecker owes its near- or complete extinction to habitat loss (logging) as well as over-exploitation by humans, who hunted it for its feathers. http://www.allaboutwildlife.com/ten-most-endangered-animals/ivory-billed-woodpecker/

Another possible candidate is the Thylacine or Tasmanian wolf, a large carnivorous marsupial.

The last one died in captivity in 1933, but sightings are reported from time to time.

The next one in the slaughter house
