Profiles, tracking data and behaviour notes on the rarest raptors on the planet — from the Philippine Eagle to the Madagascar Serpent Eagle.
With fewer than 400 breeding pairs remaining, the Philippine Eagle is one of the rarest raptors on Earth. Here's what field biologists have learned in three decades of recovery work.
The Harpy Eagle takes monkeys and sloths from the canopy with talons the size of a grizzly bear's. Yet across most of its range, it is now functionally rare.
The Secretary Bird kills snakes by kicking them with the impact of a boxer's punch. It is also disappearing from parts of Africa faster than most people realise.
The Andean Condor's ten-foot wingspan is only half the story. Its slow reproduction and long life make it both a marvel of soaring flight and an early warning system for the Andes.
The Snowy Owl is one of the few large birds most people can recognise on sight — and yet almost everything else about it, from where it will spawn to where it will winter, is genuinely hard to predict.
With fewer than 250 breeding pairs left, the Madagascar Fish Eagle is one of the most range-restricted eagles in the world. Here is why it matters and what is being done.
The Forest Owlet was missing to science for 113 years. Its 1997 rediscovery in Maharashtra opened a small window that could still close.
The Javan Hawk-Eagle is a slim, high-crested rainforest raptor and one of the world's rarest tropical eagles.
The Bearded Vulture is the only bird on Earth that lives almost entirely on bone. Its story reaches from Himalayan cliffs to the reborn colonies of the Alps.
Steller's Sea Eagle is a coastal giant with a bright yellow beak and a nine-kilo body. It hunts salmon on some of the wildest coasts on Earth.
Once a familiar scavenger across South Asia, the white-rumped vulture became a warning about the hidden costs of veterinary drugs.
A yellow-faced scavenger cracks eggs with stones, crosses continents, and faces threats that no clever feeding trick can solve.
