Critically endangered grebe found only on Lake Junín in the high Andes of central Peru. Adults are gray and white with a ruby-red eye; young birds have a brownish tinge. Extremely similar to the far more common Silvery Grebe, but Junin Grebe is slightly larger with a longer bill, a skinnier neck, darker flanks, and a paler bill. These differences are more evident when both species are present, to allow for direct comparison. Not easily seen or identified from the lakeshore; a boat is usually needed for close-up views.
