Tyrant-flycatchers (Tyrannidae)

Scissor-tailed Flycatcher (Tyrannus forficatus) - HBW 9, p. 424

French: Tyran à longue queue German: Scherenschwanz-Königstyrann Spanish: Tijereta Rosada
Other common names: Fork-tailed Flycatcher(!)

Taxonomy: M[uscicapa] forficata J. F. Gmelin, 1789, Mexico.
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. Present species long considered closest to T. savana, mainly due to tail-streamers, and both previously separated in subgenus Muscivora (and earlier in genus .. View all taxonomy...

Present species long considered closest to T. savana, mainly due to tail-streamers, and both previously separated in subgenus Muscivora (and earlier in genus Milvulus); affinity not supported by molecular-sequence data. Phylogenetic analyses indicate clade including this species and T. verticalis within “E & W species group” that also includes T. tyrannus and perhaps T. caudifasciatus and/or T. cubensis. Monotypic.

Distribution: Breeds in SC USA (SE Colorado, S Nebraska and SW Missouri S to E New Mexico and W Louisiana) S to NE Mexico (N Coahuila, C Nuevo León, N Tamaulipas). Winters S Mexico (Atlantic slope from S Veracruz to W Campeche, Pacific slope from Guerrero, and interior Chiapas), El Salvador, Honduras and Nicaragua S to C Costa Rica and rarely W Panama; also S Florida.
