American Redstart (Setophaga ruticilla) Science Article 3
In recent years certain bird taxonomists have indulged in what might be described as a veritable orgy of genus-lumping. Small genera, particularly monotypic genera, must, it seems, be somehow combined with one another, or shoehorned into larger genera (see, for example, the footnote on Uropsila, Paynter, 1960:430). To some extent this is a healthy trend, as many bird families are undeniably oversplit.
