Conservationists have helped to save North America’s largest bird from extinction, but it’s still important to give every chick a chance to fly free.

The fungus that causes white-nose syndrome continues its deadly spread west — but a meeting of bat researchers reveals cause for hope.

New research shows that 2,000-year-old baobab trees are suddenly dying. New trees won’t have a chance, either.

This small, flightless bird, native to an atoll in the Pacific, went extinct as a direct result of World War II.

As the wild population of red wolves falls to just 40 animals, captive breeding may be their last chance for survival.

Exhaustive searchers have failed to turn up the lost Algerian species Adenocarpus faurei. Could other plants in the region also be extinct?

Thanks to protective efforts in Russia, these critically endangered big cats have renewed hope of avoiding extinction.

The key to saving elephants and other species may lie in the DNA contained in their droppings, says conservation biologist Samuel Wasser.

The “extinction capital of the world” could start losing unique plant species in as little as a month if funding disappears.

Dozens of these water-filtering species are at risk of vanishing, and that’s bad news for every living creature that relies on them.
