Crested duck

Lophonetta specularoides

Gekuifde eend / Schopfente / Canard huppé

 

The crested duck is a species of duck native to South America, belonging to the monotypic genus Lophonetta. It is sometimes included in Anas, but it belongs to a South American clade that diverged early in dabbling duck evolution. 

 

There are two subspecies: 

  • L. specularioides alticola, Andean crested duck
  • L. specularioides specularioides, Patagonian crested duck

The Patagonian crested duck is also called the southern crested duck and its range lies in the Falklands, Chile, and Argentina.

It feeds on invertebrates and algae, and prefers shallow coastal regions. It nests in tall grass near water and lays 5 to 7eggs.

 

This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size may be moderately small to large, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern (IUCN, 2012).
