Fun facts

  • The male does everything: he scrapes the nest, incubates the eggs laid by several different females in the same hollow for forty days, and then raises the brood, which can number more than twenty chicks, on his own.
  • Its eggs were a staple food for the Tehuelche and Mapuche peoples of Patagonia, and the shells turn up frequently at archaeological sites across the steppe.
