Tanagra Darwinii.
This species is common at the Falkland Islands, and it often occurs mingled in the same flock with the last one. I suspect, however, it more commonly frequents higher parts of the hills. These species have a very close general resemblance; but the marks about the head, which are white in the C. melanodera, are yellow in the C. xanthogramma, while the parts of the tail-feathers which are white in the latter, are yellow in the C. melanodera: this difference of colours does not hold in the females, but they may be at once distinguished by the greater length of wing, when folded, of the C. xanthogramma.

This bird was very abundant in large flocks during May, at Maldonado; I found it also at the Rio Negro.
