Tyrant-flycatchers (Tyrannidae)

Golden-crowned Flycatcher (Myiodynastes chrysocephalus) - HBW 9, p. 412

French: Tyran à casque d’or German: Andenmaskentyrann Spanish: Bienteveo Coronidorado

Taxonomy: Sc[aphorhynchus] chrysocephalus Tschudi, 1844, Chanchamayo, Junín, Peru.
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 do suggest some strong tentative conclusions.

Taxonomy: Sc[aphorhynchus] chrysocephalus Tschudi, 1844, Chanchamayo, Junín, Peru.
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 do suggest some strong tentative conclusions. Present species and M. hemichrysus originally considered conspecific; recovered as sister-taxa under certain coding schemes of morphological characters, and as a clade with very strong bootstrap support in all analyses of molecular data. Three subspecies currently recognized.

Subspecies and Distribution:

  • minor Taczanowski & Berlepsch, 1885 - E Panama (Cerro Tacarcuna and Cerro Pirre, in Darién), W & E Colombia (throughout Andes, also La Macarena Mts in S Meta) and Ecuador (S on W slope to Alamor area of W Loja).
  • cinerascens Todd, 1912 - N Colombia (Sierra Nevada de Santa Marta) through Sierra de Perijá to mountains of W & N Venezuela (Andes, and in C Falcón coastal mountains E to Sucre and N Monagas).
  • chrysocephalus (Tschudi, 1844) - Peru (C & E Andes from San Martín S to N Puno, also recorded in W cordillera in Bosque de Cuyas), W Bolivia (La Paz S to Chuquisaca and Tarija) and extreme NW Argentina (N Salta).
