Sirirí pampa
Dendrocygna viduata
Sirirí pampa/White-faced Whistling-DuckTwo structural characteristics of sievers can be identified in the bill of this White-faced Whistling-Duck. A flared maxilla at the tip and a highly developed nail. Sievers feed separating food particles from the water. The lamellae, thin plates which line the edges of the bill, function like a strainer. They let water out and retain material food.
