One of the 23 eagles on WAnimals

Black-and-chestnut Eagle

Spizaetus isidori

Endangered

At very high risk of extinction in the wild in the near future.

Spotted something wrong?

The black-and-chestnut eagle is the great raptor of the Andean cloud forests, black and chestnut with a strongly marked upright crest. It hunts above all arboreal mammals, including monkeys, sloths and squirrels, which it surprises in the canopy. It is a low-density species that needs enormous territories of unbroken forest, and the fragmentation of the Andean forests, together with direct persecution by poultry keepers, has led to its being listed as Endangered.

Fun facts

  • It is one of the few raptors in the world specialised in hunting mammals in the canopy of montane forest: monkeys, sloths and squirrels make up most of its diet.
  • Its greatest immediate threat is not logging but shooting: it is blamed for killing chickens on Andean farms, and in several studies direct persecution caused more adult deaths than any other factor.
