The horned grebe (Podiceps auritus) is a member of the grebe family of water birds. It is also known as the Slavonian grebe. It is an excellent swimmer and diver, and pursues its fish prey underwater. P. auritus is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies.
The horned grebe is a small grebe at 31–38 cm (12–15 in) long with a 46–55 cm (18–22 in) wingspan. Unmistakable in summer, the plumage of both male and female includes a black head with brown puffy earlike tufts along the sides of its face. It shows a deep red neck, scarlet eyes, and a small, straight black bill tipped with white. It rides high in the water. source
