A Name at Last: The Chiloé Steamer-Duck

One of the enduring pleasures of birding is watching scientific discovery unfold over time. This week brought exciting news from the field: a sea duck long familiar to birders in southern Chile has finally been formally described and named—the Chiloé Steamer-Duck.

VENT guide Andrew Whittaker, Tour Leader at Victor Emanuel Nature Tours, shared the news while beginning a tour in Ghana. For more than a decade, Andrew has been introducing this distinctive bird to guests on his Chile tours. Until now, it appeared on bird lists simply as Steamer-Duck sp. novum—a placeholder name used while scientists worked to formally describe the species.

Now, after years of study, the bird has received its official name, honoring the Chiloé region of southern Chile, where it occurs along the rugged coastal waters.

VENT travelers who have joined Andrew in Chile may already remember this remarkable species. Both males and females are striking in the field, and the female’s distinctive bill coloration is especially helpful for identification. Like all steamer-ducks, the Chiloé Steamer-Duck also displays an unusual feature: a bare orange carpal bulge at the bend of the wing. This curious structure is thought to help the birds hold their position against powerful underwater currents while feeding along the coast.

Moments like this are part of what makes birding so rewarding. Even birds we have been observing for years can still surprise us with new discoveries and deeper understanding.

For Andrew—and for the many VENT guests who have seen this bird on tour—it’s gratifying to see a familiar species finally recognized. After years listed simply as sp. novum, the Chiloé Steamer-Duck now has a name.
