Order: Podicipediformes
Family: Podicipedidae
The White-tufted Grebe is a small, striking waterbird easily recognized by its contrasting black head and prominent white ear tufts. Its compact body and lobed toes make it an agile swimmer and diver. Found throughout Patagonia, this grebe is often seen in pairs or small groups on lakes, ponds, and slow-moving rivers. During the breeding season, it constructs floating nests anchored to aquatic vegetation. Its vocalizations are soft and often heard at dawn or dusk. The species is adaptable, inhabiting both natural and artificial water bodies, and is generally non-migratory, though some local movements occur in response to water levels. Its diet consists mainly of aquatic invertebrates and small fish, which it catches by diving. The White-tufted Grebe plays an important role in the aquatic ecosystems of Patagonia, helping to control insect populations and serving as an indicator of wetland health.
Habitat
Prefers lakes, ponds, marshes, and slow-flowing rivers with abundant aquatic vegetation across Patagonia.
Foraging
Dives underwater to catch aquatic insects, crustaceans, and small fish, often foraging alone or in pairs.
