From giant eagles to miniature falconets, meet the many species of raptors. Explore how they survive winters, learn to hunt and undergo migrations. Their superpowers of flight, sight, hearing and smell give them dominance over the skies.

The golden lion tamarin stands as a beacon of hope and survival in the face of extinction after an outbreak of yellow fever led to a loss of nearly a third of their wild population.

As urban expansion quickly replaces natural habitats, façade engineer Alistair Law has discovered a new way to restore native ecosystems for pollinators and create natural spaces for us all within cities – by turning the walls of buildings into meadows.

Amid collapsing biodiversity worldwide, Mary Reynolds of Ireland is building a movement to turn gardeners into guardians of the planet by returning our own patch of land to nature and by restoring hope that individual action can create lasting change.

In the face of extreme habitat loss, wildlife biologist Dr. Chris Jenkins puts an ambitious plan in motion to save two uniquely American reptiles, the eastern indigo snake and the gopher tortoise, and the forest they call home.

Three species of sea turtles nesting in southeast Florida face a range of manmade threats. Thanks to conservation measures, loggerhead and green sea turtles are recovering, but leatherbacks remain at risk. Researchers know little about this amazing species — and in the battle to save leatherbacks, knowledge is key.

For years, Derek Gow worked his 400-acres in western England as a conventional sheep and cattle farm. But as both a farmer and conservationist, he knew that wasn’t right for nature. Now, he’s using his experience with British rewilding projects to return his land to what it once was: a healthy, biodiverse ecosystem.

Crystal River has long been a safe haven for the Florida manatee, but when an invasive algae wiped out the eelgrass that manatees need for food, the community rallied to restore the river and save the animals that call it home.

Coral reefs around the world are threatened by rising ocean temperatures, but hope is growing off the coast of Hawaii. There, researchers at the Coral Resilience Lab selectively breed corals to withstand ever-increasing amounts of heat stress.

All around the world, seabirds provide a critical link between land and sea. On Hawai’i, ecologists are working to protect two vital shearwater species that helped life first take hold across these islands.

Hawai’i is home to a broad, beautiful array of bird species found only on its islands — like the stunningly diverse honeycreepers, many on the border of extinction. Now, a local team is removing invasive predators, restoring habitats, and battling mosquito-borne diseases to protect honeycreepers from their latest threat: avian malaria.

In the middle of Rio de Janeiro sits the world’s largest urban rainforest: Tijuca National park. To combat a century of deforestation and hunting, a team of researchers are repairing the forest’s forgotten web of life, one species at a time.

Follow Patrick Dykstra in his quest to connect with and understand the hidden nature of the sperm whale, shining a light on their intelligence and complexity, as well as their relationship with humankind.

Follow Sir David Attenborough and a team of forensic experts as they unearth the fossil of a giant Pliosaur, the largest Jurassic predator ever known.

Follow a conservation movement of bird-loving experts and citizen scientists as they mobilize to the challenge of understanding and saving shorebirds.
