Ovenbirds (Furnariidae)
Sharp-billed Treehunter (Heliobletus contaminatus) - HBW 8, p. 354
French: Sittine à bec fin
German: Ockerbrauen-Baumspäher
Spanish: Ticotico Estriado
Other common names: Sharp-billed Xenops, Fulvous-browed Sharp-bill
Taxonomy: Heliobletus contaminatus Berlepsch, 1885, Nova Friburgo, Rio de Janeiro, Brazil.
Species originally named as H. superciliosus, then as Anabates contaminatus, but that a nomen nudum. Genus sometimes merged into Xenops; only minor differences between the two in plumage characters, but major differences in vocalizations suggest that they are not closely related. Although both are often placed at end of traditional linear sequences, evidently because of the unusual bill and branch-foraging adaptations, it seems more likely that they were independently derived from various lineages elsewhere within Furnariidae; for example, they are reasonabl..

Species originally named as H. superciliosus, then as Anabates contaminatus, but that a nomen nudum. Genus sometimes merged into Xenops; only minor differences between the two in plumage characters, but major differences in vocalizations suggest that they are not closely related. Although both are often placed at end of traditional linear sequences, evidently because of the unusual bill and branch-foraging adaptations, it seems more likely that they were independently derived from various lineages elsewhere within Furnariidae; for example, they are reasonably similar in plumage pattern to other acrobatically foraging genera such as Premnornis, Siptornis, Anabacerthia, Syndactyla and Cichlocolaptes. Nominate race intergrades with camargoi in N São Paulo. Two subspecies recognized.
