Tyrant-flycatchers (Tyrannidae)

Black-tailed Tityra (Tityra cayana) - HBW 9, p. 450

French: Tityre gris German: Schwarznackentityra Spanish: Titira Colinegro

Taxonomy: Lanius [] cayanus Linnaeus, 1766, French Guiana.
Genus formerly included with Pachyramphus in the Cotingidae, but transferred to the present family on the grounds of several shared, derived similarities of the skull and syrinx. Because of their similarity to cotingids in respect of many other features, some authors prefer to treat both genera as representing a separate family (Tityridae) or to leave them in Cotingidae. Phylogenetic affinity of genus and of this species currently unknown; molecular investigation needed. Races differ considerably in plumage; has been suggested that they be treated as two separate species, but apparent .. View all taxonomy...

Taxonomy: Lanius [] cayanus Linnaeus, 1766, French Guiana.
Genus formerly included with Pachyramphus in the Cotingidae, but transferred to the present family on the grounds of several shared, derived similarities of the skull and syrinx. Because of their similarity to cotingids in respect of many other features, some authors prefer to treat both genera as representing a separate family (Tityridae) or to leave them in Cotingidae. Phylogenetic affinity of genus and of this species currently unknown; molecular investigation needed. Races differ considerably in plumage; has been suggested that they be treated as two separate species, but apparent intergrades occur in a belt from NE Brazil (Piauí) SW through Mato Grosso to Bolivia. Two subspecies recognized.

Subspecies and Distribution:

  • cayana (Linnaeus, 1766) - Venezuela, Trinidad, the Guianas, E Colombia, N Brazil (Amazon and tributaries E to Pará and Amapá), E Ecuador, E Peru and Bolivia.
  • braziliensis (Swainson, 1837) - NE, C & S Brazil (Maranhão, Piauí and Pernambuco S to Mato Grosso do Sul and N Rio Grande do Sul), N and E Bolivia (La Paz, Cochabamba, Santa Cruz), N, C & E Paraguay (primarily E of R Paraguay) and NE Argentina (S to E Formosa, E Chaco and Misiones, probably also Corrientes).
