パタゴニアカイツブリ Podiceps gallardoi

A beautiful, small grebe of Patagonia that is rare, local, and declining; breeds on a few interior lakes. Nonbreeding birds range to coastal waters and lowland lakes, where they are most often seen in the company of Silvery Grebes. Told from Silvery Grebe by more contrasting head pattern: black hood contrasts with white forehead and golden tiara, often striking at long range. Grebes are very rarely seen in flight, but wings of Hooded are mostly white unlike the dark wings with a white hind patch seen on Silvery Grebe.
