Dabbling ducks (Anas) to ruddy-ducks (Oxyura)

Chiloe Wigeon - Anas sibilatrix
Chiloe Wigeon
Anas sibilatrix
Trelew, Chubut province, Argentina.
Male, with the green iridescence behind the eye. It's a common freshwater duck in the southern temperate region. (S6)


Yellow-billed Teal - Anas flavirostris
Yellow-billed Teal
Anas flavirostris
Lauca National Park, Region I, Chile.
Formerly lumped with Andean Teal as Speckled Teal. The two species differ strikingly, especially in head color and bill color, and I think the split is well-deserved. (S5)


Yellow-billed Teal - Anas flavirostris
Yellow-billed Teal
Anas flavirostris
Lake Junín, Junín department, Peru.

Yellow-billed Pintail - Anas georgica
Yellow-billed Pintail
Anas georgica spinicauda
Trelew, Chubut province, Argentina.
In northern South America, this duck is restricted to the cool, high Andes. Farther south it can be found near sea level. (S6)


Yellow-billed Pintail - Anas georgica

Anas discors and Anas andium andium
El Cajas National Park, Azuay province, Ecuador.
Two female-plumaged Blue-winged Teal sitting behind a pair of Andean Teal. (S8)


White-cheeked Pintail - Anas bahamensis
White-cheeked Pintail
Anas bahamensis galapagensis
Isabela, Galapagos Islands, Ecuador.
This duck is found in the West Indies, northern South America, and disjunctly in southern South America. Northern populations seem to occur mainly near the coast, but southern bird can occur well inland. This subspecies is endemic to the Galapagos, though it is not hugely different from the mainland races (below). (S5)


White-cheeked Pintail - Anas bahamensis
White-cheeked Pintail
Anas bahamensis bahamensis
La Segua marsh, Manabí province, Ecuador.
(S8)


Silver Teal - Anas versicolor
Silver Teal
Anas versicolor fretensis
Gaiman, Chubut province, Argentina.
A handsome freshwater duck of southern South America and the Falklands. I think it's a rather odd name for the species; I suppose it's rear end might be silvery, but that's about it. (S6)


Puna Teal - Anas puna
Puna Teal
Anas puna
Huacarpay Lake, Cuzco department, Peru.
This species is similar to Silver Teal (above), and they are sometimes considered conspecific. It inhabits high Andean lakes from Peru to northern Argentina. (D7)


Red Shoveler - Anas platalea
Red Shoveler
Anas platalea
Trelew, Chubut province, Argentina.
Male. There are four species of shoveler in the world, and this is the only one that breeds in South America. It is found from southern Peru and southern Brazil south to Tierra del Fuego and the Falklands. (S6)


Red Shoveler - Anas platalea
Red Shoveler

Rosy-billed Pochard - Netta peposaca
Rosy-billed Pochard
Netta peposaca

Brazilian Merganser - Mergus octosetaceus
Brazilian Merganser
Mergus octosetaceus
Serra da Canastra NP, Minas Gerais state, Brazil.
A pair with several recently-hatched ducklings. It's the rarest duck in South America. BirdLife International (see factsheet) estimates the population to be 50-249 individuals, most of the them in Brazil. A small population was recently rediscovered in Argentina, and a few might persist in Paraguay. Canastra NP is probably the best place to see it. They can be seen on most days if you know where to look, but can be missed if you get unlucky. (D3)


Masked Duck - Nomonyx dominicus
Masked Duck
Nomonyx dominicus
Reserva Ecologica de Guapi Assu, Rio de Janeiro state, Brazil.
Female on the right, male on the left. Quite a scarce duck even though it is widespread. REGUA has become a great place to see them in the last few years. (D3)


Ruddy Duck - Oxyura jamaicensis
(Andean) Ruddy Duck
Oxyura jamaicensis ferruginea
Lake Junín, Junín department, Peru.
Eclipse (or immature) male, lacking the blue bill. (S8)


Lake Duck - Oxyura vittata
Lake Duck
Oxyura vittata
Trelew, Chubut province, Argentina.
Male. It inhabits freshwater lakes in Chile and Argentina, occasionally reaching Brazil and Paraguay in the winter. I think it has one of the worst English names of any bird; occasionally the name "Argentine Ruddy-Duck" is used, though I suggest "Southern Ruddy-Duck" might be somewhat better. (S6)


Lake Duck - Oxyura vittata
Lake Duck
Oxyura vittata
Trelew, Chubut province, Argentina.
Female. (S6)
