Tyrant-flycatchers (Tyrannidae)

Streaked Flycatcher (Myiodynastes maculatus) - HBW 9, p. 414

French: Tyran audacieux German: Südlicher Fleckenmaskentyrann Spanish: Bienteveo Rayado

Taxonomy: Muscicapa maculata Statius Muller, 1776, French Guiana.
Affinities of genus uncertain; for long hypothesized as being closest to Conopias, largely on basis of similar hole-nesting tendencies. Genus probably monophyletic, although this only weakly supported by recent analyses of molecular-sequence data (likely due to inappropriate markers for the apparently long branches and deep level of divergence within genus). Results of separate analyses of plumage/syringeal morphology and molecular data were not completely congruent, but evidence strongly suggests that present species is sister to M. luteiventris, and that the two are sister-gro..

Taxonomy: Muscicapa maculata Statius Muller, 1776, French Guiana.
Affinities of genus uncertain; for long hypothesized as being closest to Conopias, largely on basis of similar hole-nesting tendencies. Genus probably monophyletic, although this only weakly supported by recent analyses of molecular-sequence data (likely due to inappropriate markers for the apparently long branches and deep level of divergence within genus). Results of separate analyses of plumage/syringeal morphology and molecular data were not completely congruent, but evidence strongly suggests that present species is sister to M. luteiventris, and that the two are sister-group to a clade consisting of M. hemichrysus and M. chrysocephalus. Has been suggested that race solitarius may represent a separate species, on basis largely of differences in plumage, but apparent intermediate forms from N Brazil (S Amazonas) and general similarity in voice to other races argue against this. Otherwise, clearly observable differences between supposed races from localities as widely separated as N Venezuela, the Guianas and NE & S Brazil are lacking; close re-evaluation and probably revision required. Seven subspecies currently recognized.

Subspecies and Distribution:

  • insolens Ridgway, 1887 - breeds E & SE Mexico (SW Tamaulipas S to Puebla, N Oaxaca and N Chiapas, E to S Yucatán and Quintana Roo), N Guatemala, Belize and NW Honduras; migrates S to N South America.
  • difficilis J. T. Zimmer, 1937 - W Costa Rica S to Panama (including Coiba I and Cébaco), Colombia (except N & W) and W Venezuela (W of Andes in Zulia and Táchira, W Falcón E to Curimagua, and E base of Andes S from Portuguesa).
  • nobilis P. L. Sclater, 1859 - N Colombia (Córdoba E in coast region to Sierra Nevada de Santa Marta and W side of Sierra de Perijá).
