Tyrant-flycatchers (Tyrannidae)

Sooty-crowned Flycatcher (Myiarchus phaeocephalus) - HBW 9, p. 435

French: Tyran à front gris German: Rußkappen-Schopftyrann Spanish: Copetón Tiznado

Taxonomy: Myiarchus phaeocephalus P. L. Sclater, 1860, Babahoyo, Ecuador.
Phylogenetic analysis of mitochondrial DNA found one phenotypically typical individual of race interior more closely related to clade formed by M. venezuelensis, M. panamensis and M. ferox than to two nominate individuals of present species. Further study of decoupled molecular and morphological evolution needed. Races weakly differentiated. Two subspecies recognized.

Subspecies and Distribution:

  • phaeocephalus P. L. Sclater, 1860 - W Ecuador (S from N W Esmeraldas and W Pichincha) and NW Peru (S to Lambayeque).
