Netta erythrophthalma
This rather large, dark brown duck with its blue bill and red eyes is a common resident and local nomad at lakes and ponds through much of southern Africa.
We first recorded it in March 2010 on the Amersfort / Utaga Bridge near Wakkerstroom, Mpumulanga. Marievale Bird Sanctuary, specifically the Hadida Hide, is a reliable spot for this species.
