Song of the Mountain Chicken

These giant frogs—once a delicacy on two Caribbean islands—were almost wiped out by disease and natural disasters. But their resilience and years of dedicated conservation efforts have kept hope for the species alive.

The Secret Garden

The crystalline rivers of the Serra da Bodoquena offer a window into Brazil’s freshwater biodiversity. But with deforestation on the rise, that window is becoming cloudier.

Captured on July 5, 2018, this was the first photograph to document pollination of a ghost orchid bloom. Contrary to the expectations of many experts, who believed that the giant sphinx moth was likely the only pollinator of the ghost orchid, this moth is a fig sphinx.

Ghosts of the Everglades

Clinging to survival in shrinking swamps, ghost orchids are so elusive that their pollinators have remained unknown—until now. One team’s findings may help to save both the flower and its threatened home.

California’s Chinook salmon have been losing habitat to agriculture for decades. Now, they’re getting a much-needed boost from strategically flooded fields.

<strong>Taking Center Stage by Audun Rikardsen</strong><em>—Grand Prize Winner</em>
<p>While the beauty of Norway’s spectacular northern coastline might be lost on this male black grouse (Tetrao tetrix), the prime vantage point offered by its perch is certainly not. For a ground-dwelling bird known for exuberant territorial displays during the breeding season, what better place to see and be seen than this branch, which provides an eagle’s-eye perspective of the terrain below. What initially drew photographer Audun Rikardsen to this spot high above the sea was, in fact, a resident golden eagle (Aquila chrysaetos) that frequented the perch. Having constructed a blind nearby, Rikardsen spent many frigid winter days photographing the eagle. But by spring, it had been replaced by a new subject: a black grouse in proud display. Not only did the grouse quickly become accustomed to Rikardsen’s rapidly firing camera shutter and flash, he says, it was almost as if the bird enjoyed being in the spotlight.</p>
The Big Picture 2019

From the beautiful to the bizarre, this photographic showcase of life on Earth shines a light on some of our planet's most amazing species and places.

A platypus (Ornithorhynchus anatinus) pauses for a moment after being released by scientists into the Little Yarra River, its home stream in Victoria, Australia.
Plight of the Platypus

The more scientists learn about this strange, elusive species, the more concerned they become about its future. But these new insights may ultimately help to save it.

Dalmatian pelicans (Pelecanus crispus)
Below the Bill

One of the world’s largest birds has long been persecuted for both its outsized bill and its eating habits, but an ambitious cross-border plan is helping this threatened pelican bounce back.

Migratory fish like these mountain mullet (Agonostomus monticola) are a common sight in Central American rivers.
Free-Flowing, For Now

Hundreds of new dams are currently planned for Central American rivers, posing a threat to Indigenous peoples and wildlife alike. Preserving the integrity of these corridors between the mountains and the sea will help them both.
