Captive Breeding

The gigantic Ozark hellbender salamander is in trouble in the wild, but one zoo — and a hard-working team — is helping to boost its populations.

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.

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

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

With just a few dozen left in the wild, things don’t look good for these critically endangered birds. But a captive-breeding program could help save them.

Only 35 Mount Graham squirrels remain in the wild, but five captive squirrels could hold the key to their long-term survival — if we can get them to breed.

The last 150 birds of this critically endangered species rely on humans for their survival.
