Uppucerthia rupestris, D’Orb. & Lafr. Mag. de Zool. 1838, p. 21.

This bird is extremely common on the sea shore of all the bays and channels of Tierra del Fuego; on the western coast it is replaced in Northern Chile by the O. nigrofumosus, and in the Falkland Islands by the O. antarcticus. As the habits of this species and those just named are quite similar, I shall describe them all together under the head of O. nigrofumosus. A specimen of O. Patagonicus from Chiloe has a bill rather more than two-tenths of an inch longer than in those from Tierra del Fuego; but as no other difference can be perceived, I cannot allow that this is a specific character any more than in the case of the Uppucerthia.

This species inhabits the Falkland Islands. My specimens were procured at the east island, from which, also, those described by the French naturalists came, and likewise that given in the Appendix to Dixon’s Voyage. I have no doubt that it is peculiar to this group, for the foregoing species, which in the neighbouring mainland of Tierra del Fuego supplies its place and has precisely the same habits, has been examined by Mr. Gould and is considered distinct. The O. antarcticus has long been noticed by voyagers to the Falkland Islands from its extreme tameness: in the year 1763 Pernety states it was so tame that it would almost perch on his finger, and that in half an hour he killed ten with a wand.
