Chubut Steamer-duck

The Chubut Steamer-duck is a large, flightless duck endemic to Argentina’s Atlantic coast. It occurs along the coast of Chubut, with breeding also documented in Santa Cruz (Imberti, 2003). It uses its short wings and powerful feet to 'steam' across the water. Adult males are larger and often appear white-headed, with an orange bill; females are smaller and browner-headed, with a broad white postocular stripe and a darkish bill. The species is highly territorial and is often seen in pairs or family groups. It is globally classified as Vulnerable, reflecting its restricted coastal range.
