Miro traversi and **"Petroica traversi"** actually refer to the *same* bird: the Chatham Island black robin.
Here’s the breakdown: * **Petroica traversi** is the bird’s **current accepted scientific name**. * **Miro traversi** is an **older name** (a synonym) that was once used in taxonomy but has since been replaced. * Common name: **Black robin** or **Chatham Island black robin**.
This little bird is famous for having been *rescued from the brink of extinction* — in 1980 there were only **five individuals left**, including just one breeding female nicknamed “Old Blue.” Thanks to intensive conservation work in New Zealand’s Chatham Islands, their population has recovered to several hundred.

The whole of the plumage black, the base of the feathers dark plumbeous; wing-feathers and their coverts tinged with brown, the former greyish on their inner surface; tail-feathers black, very slightly tinged with brown. Irides dark brown; bill black; tarsi and toes blackish brown, the soles of the feet dull yellow. Total length 6 inches; wing, from flexure, 3.4; tail 2.6; bill 0.5, tarsus 1.1; middle toe and claw 0.1, hind toe and claw 0.8 inch." "Female. Slightly smaller than the male, and without the brown tinge on the wings and tail." It may be added that ''Miro traversi'' is not pure black, but of a somewhat brownish slaty black. ''Miro traversi'' is only known from the Chatham Islands, where it was formerly very common, but, according to a letter from the late W. Hawkins, the cats, which have been introduced to destroy rats and rabbits, have exterminated it. It seems to have disappeared from Warekauri, the main island of the Chatham group, long ago, for H. O. Forbes (Ibis 1893, p. 524) and Henry Palmer found it, in 1890 and 1892, only on the outlying islets of Mangare and Little Mangare. The bird from the Snares is quite different, being deep glossy black and having a shorter and narrower first primary. I named it ''M. dannefaerdi''. It is to be feared that a similar fate will one day befall it as has, apparently, already befallen its congener from the Chatham Islands. Sir Walter Buller (Suppl. B.N.Z. II, p. 125) has confounded ''M. traversi'' and ''dannefaerdi'', and the figure he gave on his plate looks so black, that I do not doubt it represents rather the latter than the former. Of course ''M. dannefaerdi'' alone occurs on the Snares, and Buller's ''traversi'' from the Snares were all dannefaerdi. Dr. Finsch's statement (Ibis 1888, p. 308) that Reischek's specimen from the Snares "agreed in every respect with specimens from the Chatham Islands" is entirely wrong, for, even if
