The Patagonian or Burrowing Conures, from southern Argentina, southern Chile and Uruguay, are unusual for parrots in that they burrow into cliffs for nesting.
They are also known as Cliff-dwelling Conures or Parakeets.
The male and female have similar plumage. Their underside is colourful.
There are 3 subspecies:
the (Lesser) Patagonian (all above) Cyanoliseus patagonus patagonus, the most common, with a white shoulder stripe and one of the largest conures at 45 cm long,
. . . the less colourful Andean Patagonian, Cyanoliseus patagonus andinus (above),
. . . and the largest of all conures (up to 48 cm long), the Greater Patagonian (above/below), Cyanoliseus patagonus bloxami/byroni, with its full white necklace.
"Cyanoliseus" refers to the blue flight feathers of the species.
The Greater Patagonian doing some "Burrowing".
