Field notes

  • Despite its name, it is technically a large hawk (buteonine) rather than a true eagle.
  • Adults display a striking plumage contrast between a dark slate-grey upper body/chest and a white, finely barred belly.
  • The species' scientific name combines 'geranos' (crane) and 'aetos' (eagle), referring to its greyish coloration.
  • In flight, its extremely short tail gives it a distinctive 'tailless' silhouette compared to other large soaring birds.
  • They are known to engage in spectacular aerial courtship displays involving steep dives and mutual talon-locking.
Habitat
Open montane grasslands, rocky ridges, shrublands, and semi-arid canyons.
Range
South America, ranging along the Andes from Venezuela to Tierra del Fuego, as well as parts of eastern Brazil and Paraguay.
