Tyrant-flycatchers (Tyrannidae)

Social Flycatcher (Myiozetetes similis) - HBW 9, p. 407

French: Tyran sociable German: Rotscheitel-Maskentyrann Spanish: Bienteveo Sociable
Other common names: Vermilion-crowned Flycatcher

Taxonomy: Muscicapa similis Spix, 1825, mouth of River Madeira, Brazil.
Morphological and behavioural evidence suggests genus most closely related to Legatus; nesting behaviour links with Pitangus. Molecular data support clade consisting of present species and M. cayanensis as sister-group to one formed by M. granadensis and M. luteiventris. Present species may be better split: race grandis, with restricted range, differs vocally from widespread nominate; N races primulus, hesperis and texensis may form a separate species. Proposed races connivens (Urubamba) and fiedleri (Ucayali) includ.. View all taxonomy...

Morphological and behavioural evidence suggests genus most closely related to Legatus; nesting behaviour links with Pitangus. Molecular data support clade consisting of present species and M. cayanensis as sister-group to one formed by M. granadensis and M. luteiventris. Present species may be better split: race grandis, with restricted range, differs vocally from widespread nominate; N races primulus, hesperis and texensis may form a separate species. Proposed races connivens (Urubamba) and fiedleri (Ucayali) included in nominate. Seven subspecies recognized.

  • primulus van Rossem, 1930 - W Mexico (S Sonora S to N Sinaloa).
  • hesperis A. R. Phillips, 1966 - W Mexico (C Sinaloa and S Zacatecas E to SW Puebla, S at least to SE Oaxaca).
  • texensis (Giraud, 1841) - E & S Mexico (from SW Tamaulipas S through Yucatán Peninsula), Belize, much of Guatemala, El Salvador, Honduras, Nicaragua and Costa Rica (except SW).
