Hooded Grebe

Podiceps gallardoi

Critically Endangered

It faces an extremely high risk of imminent extinction in the wild. See full glossary

The hooded grebe is a grebe endemic to the Argentine province of Santa Cruz, discovered by science in 1974. It breeds on high-altitude lagoons of the Patagonian plateaus, on floating nests anchored to clumps of vinagrilla, and spends the winter on a few estuaries of the Atlantic coast. Its population has fallen by more than 80% since the 1980s because of the introduction of rainbow trout and the American mink, the drying out of lagoons and predation by kelp gulls.

Fun facts

  • It was not discovered until 1974, one of the last large vertebrates described in South America, and in barely fifty years it has gone from scientific novelty to one of the most threatened birds on the continent.
  • Its nest is a floating platform built on clumps of vinagrilla, an aquatic plant that grows only in certain plateau lagoons: without that plant, the species cannot breed.
