Poor Judge of Pasta.
I have a tentative identification in mind, but though I'd see what others thought. Taken a few days ago in Ibera, Corrientes, I saw 4 - 5 scattered up to 6 km apart, with varying amounts of black on the face (this was about average, on one the black extended further down the throat and appeared more solid). Habitat was miles of open tall marshy grassland with occasional patches of woodland and open water.
