Hi John et alia: Each spring and fall we get reports of "Newfoundland robins," but there really isn't such a thing. I have gone over this situation before on naturens, so many may want to tune out. Possibly the local notions about "Newfoundland robins" come from comments in Robie Tufts' first (1961) edition, which was carried over unchanged into the last (1986) edition. This in turn was based on the first description of the bird based the first couple of specimens were obtained from Newfoundland. According to recent information, however, it doesn't nest on the island with any frequency; most are like ours. If there is a "real" subspecies _nigridius_ of black-backed Am. Robin, its "core range" is on the Ungava Peninsula, and especially farther north. However, black-backed individuals breed more widely, even in NS, as Tufts noted. I once had a male feeding young on my street in Halifax. Some recent recent accounts have "black-backed robins" as merely darker individuals in a "cline" in darkness from south to north in eastern Canada. That's not to say that black-nacked individuals don't occur and that they are not of interest in seeing, for example, if they winter here (few if any do) and whther numbers arrive among the first in spring (they don't seem to). So John, male robins in general have black heads, so if they also have gray backs, they're local or probably migrants of the same subspecies that nests here. Your individual in which "the change in colour from body to head was very gradual," however, may have been (if blackish on the back) a "black-backed." Another good mark of "black-backed" birds is their very darkly streaked throat; it's often hard to see any white.
