Tyrant-flycatchers (Tyrannidae)

Grey Kingbird (Tyrannus dominicensis) - HBW 9, p. 423

French: Tyran gris German: Grauer Königstyrann Spanish: Tirano Dominicano

Taxonomy: [Lanius Tyrannus] dominicensis J. F. Gmelin, 1788, Santo Domingo, Dominican Republic.
Closest relatives of genus may be Empidonomus and Tyrannopsis; recent molecular-sequence data indicate present genus is monophyletic and sister-group to clade that includes Empidonomus and Griseotyrannus; two main clades within genus, loosely corresponding to “tropical species assemblage” and combination of “W” & “E” species groups of earlier authors, but with some exceptions. Phylogenetic analyses indicate that present species is sister to T. melancholicus, the two nested within an expanded “tropical species assemblage” as sister-group t.. View all taxonomy...

Taxonomy: [Lanius Tyrannus] dominicensis J. F. Gmelin, 1788, Santo Domingo, Dominican Republic.
Closest relatives of genus may be Empidonomus and Tyrannopsis; recent molecular-sequence data indicate present genus is monophyletic and sister-group to clade that includes Empidonomus and Griseotyrannus; two main clades within genus, loosely corresponding to “tropical species assemblage” and combination of “W” & “E” species groups of earlier authors, but with some exceptions. Phylogenetic analyses indicate that present species is sister to T. melancholicus, the two nested within an expanded “tropical species assemblage” as sister-group to an unresolved clade consisting of T. albogularis, T. couchii and T. savana. Race vorax only weakly differentiated. Two subspecies currently recognized.
