Sentence First, we learn how the robin (and its distant American cousin—not closely related)
got its name. Prior to scientific and ordered
taxonomy, in fifteenth century England—and elsewhere—it was common practise to give familiar species human names, this companionable nomenclature enduring in some of the more common monickers, like magpies from flocks originally called Margarets or a
daw named Jack, and Robin Redbreast—from the diminutive form of Robert and their distinctive, easily recognisable orange plumage, the colour
unknown and not distinguished until the introduction of the fruit about a hundred years later. More from Bird History at the link up top.
