Cattle Tyrant (Machetornis rixosa) - HBW 9, p. 405
French: Moucherolle querelleur
Taxonomy: Tyrannus rixosus Vieillot, 1819, Paraguay.
Affinities uncertain; molecular and anatomical evidence suggests that superficial resemblance to Tyrannus is due to convergence. Race obscurodorsalis possibly better merged with flavigularis; overlaps with latter in Venezuela and does not appear to be evolutionarily distinct; closer examination necessary. Also, some specimens of nominate from NE Brazil (Piauí) closely approach flavigularis. Three subspecies currently recognized.
Subspecies and Distribution:
- flavigularis Todd, 1912 - E Panama, N & E Colombia (N Chocó and upper R Sinú E to Guajira, S to S Bolívar) and N Venezuela (E to Guárico, W Anzoátegui and Delta Amacuro, S to N Bolívar).
- obscurodorsalis Phelps, Sr & Phelps, Jr, 1948 - SW Venezuela (Barinas, W Apure and S Cojedes), E Colombia E of Andes (Norte de Santander S to S Meta and Vichada) and E Ecuador.
- rixosa (Vieillot, 1819) - E & S Brazil (extreme NE Pará E to Rio Grande do Norte, and S to Rio Grande do Sul, also S from S Mato Grosso and Goiás), N & E Bolivia (Beni and Santa Cruz S to Tarija), Paraguay, most of N Argentina (S to San Luis, Córdoba and SW Buenos Aires) and Uruguay.
