Tyrant-flycatchers (Tyrannidae)

Venezuelan Flycatcher (Myiarchus venezuelensis) - HBW 9, p. 433

French: Tyran du Venezuela German: Venezuelaschopftyrann Spanish: Copetón Venezolano
Other common names: Fierce Flycatcher

Taxonomy: Myiarchus venezuelensis Lawrence, 1865, Lago de Valencia, Carabobo, Venezuela.
Formerly treated as a race of M. ferox. Analyses of morphological characters and mitochondrial DNA indicate close affinities with that species and also with M. phaeocephalus and M. panamensis, but precise relationships within that group unclear. In study of phylogeny of genus, mtDNA of a single individual of present species examined was nested within M. ferox, suggesting past hybridization between the two, or incomplete sorting of mtDNA in this group of species, or misidentification (as no voucher was available).

Taxonomy: Myiarchus venezuelensis Lawrence, 1865, Lago de Valencia, Carabobo, Venezuela.
Formerly treated as a race of M. ferox. Analyses of morphological characters and mitochondrial DNA indicate close affinities with that species and also with M. phaeocephalus and M. panamensis, but precise relationships within that group unclear. In study of phylogeny of genus, mtDNA of a single individual of present species examined was nested within M. ferox, suggesting past hybridization between the two, or incomplete sorting of mtDNA in this group of species, or misidentification (as no voucher was available). Careful ecological and genetic study of these species in zones of parapatry and sympatry should be rewarding. Tobago birds appear darker dorsally, but difference slight and constancy of this character untested; subspecific separation as insulicola unwarranted at present. Monotypic.

Distribution: Apparently three, possibly four, disjunct populations. Caribbean lowlands of Colombia (N Sucre E to Guajira), and E of Andes in Norte de Santander (Cucutá); NW & N Venezuela (Zulia; and far E Falcón and E Yaracuy E through lowland Carabobo and Aragua to Distrito Federal, E to Puerto La Cruz); and recorded also NE & E Venezuela (Margarita I; NE Bolívar) and Tobago. Records from Zulia (Cerro Alto del Cedro, La Esperanza) may be referable to Colombian population (to W) or to Venezuelan ones (to E), or may represent a separate population.
