My third post almost finishes the water birds and adds the South American equivalents of the ostrich, spurfowls and francolins, plus a couple of guans.

First, three that you will recognise.

Anhinga (Anhinga anhinga) [Ibera] first cousin to the African Darter (Anhinga rufa) - this one an immature bird.



Neotropic Cormorant [Ibera] first cousin to the Bank, Cape and White-breasted (but not Reed) Cormorants.



White-faced Whistling Duck [Ibera]



Muscovy Duck [Ibera] - showing its regular habit of perching in trees



Brazilian Teal - commonest duck in the Ibera Marshes; a pair (male with red bill) and a male in flight





Giant Wood Rail [Ibera] - another very common bird in the marsh fringes and surrounding grasslands



Southern Screamer [Ibera] - this odd-looking bird is surprisingly related to ducks, geese and swans; it belongs to the Anhimidae one of the three families comprising the Order Anseriformes, the others being the Anatidae Swans, Ducks and Geese and Anseranatidae the monotypic Magpie Goose.





Least Grebe [Iguassu]



Now the South American "ostrich", the Greater Rhea



The tinamous and nothuras fill the ecological niche of the African spurfowl and francolins, but belong to a completely different Order, the Tinamiformes rather than Galliformes.

Red-winged Tinamou [Ibera]



Spotted Nothura [Ibera]



Finally a couple of guans, which despite less of a physical resemblance (guineafowl-sized birds) and the fact that they are forest gallery dwellers, are more closely related to francolins and spurfowls than the tinamous and nothuras

Not the best of shots, but he wasn't moving any time soon, a Rusty-margined Guan [Iguassu]



...and an Endangered species; this male Black-fronted Piping Guan was busy with a duet call with a very well hidden female
