The Plumbeous Sierra-finch is distributed in the Andes from Colombia and Venezuela in the north to Tierra del Fuego in the south. See the distribution map at Birdlife International. It is found on rocky slopes at high altitudes and is often associated with water.

Male Plumbeous Sierra-finch, Cajon del Maipo, Chile, November 2005 - click for larger image In the case of photos 1 and 2 this male was feeding off seeds that it was finding at the edge of the snow melting in the spring sunshine in the Cajon del Maipo.

The male is a uniform grey with a hint of brown on the primaries. The female in photos 3 and 5 is heavily streaked with brown.

Female Plumbeous Sierra-finch, Laguna de Laja NP, Chile, November 2005 - click for larger image Photos 1 to 3 were taken in the Cajon del Maipo, Chile while photo 4 was taken on the Nevado del Ruiz, Colombia and photo 5 in the Chingaza NP, Colombia. Note that the leg colouring is grey in the Chilean birds and pinkish in the Colombian birds. I can find no reference to this in the literature but I note that the illustration in HBW shows grey legs while that in Ridgely & Tudor shows pinkish legs. There is considerable variation particularly in the female plumage so I assume that this is just another variation.
