Ovenbirds (Furnariidae)

Streaked Xenops (Xenops rutilans) - HBW 8, p. 356

French: Sittine striée German: Strichelscheitel-Baumspäher Spanish: Picolezna Rojizo

Taxonomy: Xenops rutilans Temminck, 1821, Brazil.
Geographical variation over species’ large range slight, despite number of named races; in fact, there seems to be more variation within nominate than among many of proposed races. Highly likely that many or most races are not diagnosable; majority were described from few specimens and few localities, and many of the characters used to define them seem invalid. Racial identity of birds from extreme E Peru and NE Bolivia (Pando) and others from extreme E & SE of latter country uncertain; the first are tentatively included with purusianus and the second with connectens.

Taxonomy: Xenops rutilans Temminck, 1821, Brazil.
Geographical variation over species’ large range slight, despite number of named races; in fact, there seems to be more variation within nominate than among many of proposed races. Highly likely that many or most races are not diagnosable; majority were described from few specimens and few localities, and many of the characters used to define them seem invalid. Racial identity of birds from extreme E Peru and NE Bolivia (Pando) and others from extreme E & SE of latter country uncertain; the first are tentatively included with purusianus and the second with connectens. Listed distributions of several races should be interpreted with caution. Eleven subspecies very tentatively recognized.
