Tyrant-flycatchers (Tyrannidae)

Baird's Flycatcher (Myiodynastes bairdii) - HBW 9, p. 413

French: Tyran de Baird German: Pazifischer Maskentyrann Spanish: Bienteveo de Baird

Taxonomy: S[aurophagus] bairdii Gambel, 1847, California; error = Guayaquil, Ecuador.
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). Findings from separate analyses of plumage/syringeal morphology and molecular data were not completely congruent, but evidence indicates that present species is basal to two main clades, one containing M. hemichrysus and ..

Taxonomy: S[aurophagus] bairdii Gambel, 1847, California; error = Guayaquil, Ecuador.
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). Findings from separate analyses of plumage/syringeal morphology and molecular data were not completely congruent, but evidence indicates that present species is basal to two main clades, one containing M. hemichrysus and M. chrysocephalus and the other M. luteiventris and M. maculatus. Monotypic.

Distribution: SW Ecuador (C Manabí, from N side of Bahía de Caráquez, S to El Oro and W Loja) and NW Peru (S on Pacific slope to Ancash and to N Lima).
