Falkland Steamer Duck

Identification

The Falkland steamer duck is a fairly large duck, measuring between 61 and 74 cm in length with a wingspan of 84 to 94 cm. Males are distinctive with brown to grey plumage and a contrasting light grey-white head, featuring a characteristic orange bill, white eye-ring, and faint white eye-streak. Females are darker overall, with a brown neck and head, olive green beak, and the same distinctive white eye-ring with a white line behind the eyes. Both sexes display characteristic yellow-orange feet. Juveniles can be distinguished from females by black marks on their paler feet and a lack of or very reduced white line behind the eyes.

In the field, the Falkland steamer duck can be confused with the flying steamer duck, with which it shares its range. However, the Falkland steamer duck has noticeably shorter wings and tail, along with a thicker neck and bill. Most significantly, the Falkland steamer duck is strictly flightless, though this characteristic can be difficult to observe since the flying steamer duck rarely takes to the air and is often seen walking or swimming.

Range & Habitat

The Falkland steamer duck is one of only two bird species endemic to the Falkland Islands in the South Atlantic Ocean, the other being Cobb's wren. This species is part of the genus Tachyeres, which contains four steamer duck species found in South America. The Falkland steamer duck is most closely related to the flying steamer duck, which can also be found in and around the Falkland Islands.

Behaviour & Diet

The steamer ducks derive their name from their unconventional swimming behaviour, in which they flap their wings and feet on the water in a motion reminiscent of an old paddle steamer. According to Charles Darwin's observations from 1833, these birds move very quickly through the water, using their wings partly for swimming and partly for flapping the surface—a motion somewhat resembling how a domestic duck escapes from a pursuing dog. The steamer is able to dive only to a very short distance.

The species feeds entirely on shellfish from kelp and tidal rocks. This diet has shaped their distinctive heavy and strong head and beak, adaptations necessary for breaking open shells. Notably, Darwin recorded that these birds are remarkably tenacious of life. When in the evening, pluming themselves in a flock, they produce an odd mixture of sounds.

Best Time & Places to See It

The Falkland steamer duck's distribution is limited to the Falkland Islands. As an endemic species found nowhere else in the world, a visit to these remote South Atlantic islands is essential for observing this unique duck. Look for them in coastal areas near kelp beds and tidal rocks, which provide their primary food source.

Photography Tips

The distinctive plumage differences between males and females offer rewarding photographic opportunities. Males' contrasting light grey-white heads and orange bills stand out dramatically against their brown-grey bodies, while females' darker colouration provides a different aesthetic challenge. The characteristic white eye-ring and eye-streak visible in both sexes can make for striking close-up portraits. Capture the birds' famous "steaming" behaviour as they flap their wings across the water—a dynamic and visually distinctive activity that defines the species. The yellow-orange feet of both sexes add a splash of colour worth highlighting in your shots.
