White-winged Coot

Another lifer today, the White-winged Coot, Fulica leucoptera, Sp. Gallareta Chica. Still in San Luis, where I visited the salinera Bebedero, a huge salt lake. Good days birding, lots of sightings, but few photos. I think my long lens may need recalibrating, something I may have to wait until mid-January before as there is nowhere in Argentina to do it.
