Tyrant-flycatchers (Tyrannidae)

Southern Scrub-flycatcher (Sublegatus modestus) - HBW 9, p. 311

French: Tyranneau modeste German: Südlicher Strauchtyrann Spanish: Mosquero Matorralero Sureño

Taxonomy: M(uscipeta) modesta Wied, 1831, Camamú and Bahia, Brazil.
Unpublished molecular data suggest that genus is closely related to Suiriri islerorum. All members of genus formerly treated as conspecific, but vocal and plumage data support existence of three species, possibly more; additional study needed in order to resolve species limits. Birds in highlands of Bolivia, which are longer-winged but resident, may represent an unnamed cryptic species. Two subspecies recognized.

Subspecies and Distribution:

  • modestus (Wied, 1831) - C Peru (Urubamba Valley) and N Bolivia E through S Brazil (E to Maranhão, Pernambuco and Paraná).
  • brevirostris (d’Orbigny & Lafresnaye, 1837) - breeds S Bolivia and Paraguay S to N Argentina (S to Buenos Aires and Mendoza) and E to Uruguay; regular non-breeding visitor N to E Peru and C Amazonia.
