Spotted something wrong?

The black-chested buzzard-eagle is one of the most widespread raptors in South America: it ranges from the Colombian Caribbean to Tierra del Fuego. It is heavily built and broad-winged, the adult slate grey on the back and breast, the juveniles brown and very different. It hunts rodents, hares, birds and reptiles, and uses the thermals of the Andean slopes to soar for hours. It is commonly seen perched on posts and cliffs on the Patagonian steppe.

Fun facts

  • Its silhouette in flight is unmistakable: the tail is so short and the wings so broad that at a distance it looks like a triangle, more like a vulture than an eagle.
  • Adults and juveniles are so different that for a long time they were described as separate species: the young bird is streaked brown and takes four years to acquire the adult's slate grey.
