Show • BIRDS. 97 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. xantlwgramma, 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. xantlwgramma.
