The Carbonated Sierra-Finch (Phrygilus carbonarius), to the untrained eye, is easily confused with a House Sparrow or Rufous-collared Sparrow. During courting behavior the male’s plumage will darken, differentiating it from the female. With their nest close by, we have observed a darker male in the sand dunes behind Del Nomade, flying from bush to bush with its mate. This tiny bird can be found throughout the Peninsula Valdes and easily observed in Punta Norte, if quiet, it is curious and not easily frightened.
