We have said elsewhere on Extinction.in that there are well over 5,000 species of officially Endangered or Threatened animals and birds on our planet. With this post, we will be providing you with ongoing and constantly updated population estimates and other information concerning the status of some of the Endangered, Threatened and Vulnerable species that are of special public concern—as well as statistics and status info on creatures that we think are special, in spite of their not being well known.

Endangered Species By The Numbers

Unless otherwise noted, all endangered species status information and population figures are taken from the IUCN Red List of Threatened Species. Listings are alphabetical, by common name.
