Tyrant-flycatchers (Tyrannidae)

Rose-throated Becard (Pachyramphus aglaiae) - HBW 9, p. 460

French: Bécarde à gorge rose German: Rosenkehlbekarde Spanish: Anambé Degollado

Taxonomy: Pachyrhrynchus Aglaiae Lafresnaye, 1839, vicinity of Jalapa, Veracruz, Mexico.
Genus formerly included with Tityra in the Cotingidae, but transferred to present family because of several shared, derived features of the skull and syrinx. Because both genera exhibit similarity to cotingids in many other features, some authors prefer to leave them in that family or to treat them as representing a separate family (Tityridae). Phylogenetic affinity of present species unknown. Has been suggested that it is closely related to P. homochrous, P. minor and P. validus, or even conspecific with first two; all are sometimes combined in a separate genus, <.. View all taxonomy...

Taxonomy: Pachyrhrynchus Aglaiae Lafresnaye, 1839, vicinity of Jalapa, Veracruz, Mexico.

Phylogenetic affinity of present species unknown. Has been suggested that it is closely related to P. homochrous, P. minor and P. validus, or even conspecific with first two; all are sometimes combined in a separate genus, Platypsaris, differing from present genus in nest shape and placement, as well as in some vocal and minor morphological characters. Racial variation poorly understood; revision clearly necessary. Eight subspecies currently recognized.

Subspecies and Distribution:

  • albiventris (Lawrence, 1867) - SW United States (SE Arizona), W Mexico (Sonora and Pacific slope from S Sinaloa S to N Guerrero, also up river valleys E to Chihuahua, Zacatecas and Morelos).
  • insularis (Ridgway, 1887) - Tres Marías Is, off W Mexico (Nayarit).
  • gravis (van Rossem, 1938) - extreme S USA (S Texas) and coastal region of NE Mexico (Tamaulipas S to Nuevo León and San Luis Potosí).
