Durnford found this species common and abundant on the Chupat River and
in the interior of Patagonia. It has a pretty song, and sings in the
evening and during the night when the moon is shining. It nests among
coarse grass and herbage, making an unpretending structure of the former
material, which is lined with fibres. It lays four eggs, pale green,
thickly striated with light reddish-brown spots running into each other,
and most numerous at the large end.
