The rest of their plumage includes mostly grey bodies and white bellies. While the male is molting his bill turns to a duller yellow/orange. Adult female Chubut steamer ducks have brown heads and necks with small white line going from the back of the eye to the fore-neck. Their bills have a greenish/yellow color. The Adult female Chubut steamer duck looks very similar to the juvenile.

Distribution Area

The Chubut steamer duck was originally thought to only be found strictly in the southern coast of the Chubut province in Argentina. However it is now known to have a larger range from the southern portion of the San Matías Gulf to Islote Chato. The crucial populations for this species are found in Bahía San Gregorio (Argentina) [1], Bahía Melo [2], and Caleta Malaspina[3]. These three crucial populations are all located in the San Jorge Gulf.

Species Status

Chubut steamer Ducks face many threats such as oil exploration, habitat destruction, predation, and invasive species. Other forms of threats they face are from guano, macroalgae and egg harvesting. There have been three major oil spills in the past 30 years that affected the ducks breeding areas by directly being coated with oil and polluting the substrate that the ducks make their nests on. The three main invasive species affecting the Chubut steamer ducks are Carcinus maenas (Green Crab), Wakame (Asian Kelp or Undaria pinnatifida) and Balanus glandula (Acorn Barnacle). These invasive species indirectly affect the duck by altering the environment that it lives in. Sub-marine predators of this species include the South American sea lion (Otaria byronia) and Killer whale (Orcinus orca). The two species that are commonly observed preying on Chubut Steamer duck eggs are the Kelp gull (Larus dominicanus) and Crested caracara (Caracara plancus). Egg harvesting has only been reported in low numbers and is not as large of a threat as others mentioned.
