The cattle tyrant (Machetornis rixosa) is a species of bird in the tyrant flycatcher family Tyrannidae. In Brazil, it is called suiriri-cavaleiro. It is the only member of the genus Machetornis. The relationships of this species and genus to other genera in the tyrant flycatchers are uncertain. It resembles Tyrannus flycatchers, but this may be the result of convergence.
The genus name was given to the species by George Robert Gray and is derived from the Ancient Greek makhētēs for fighter and ornis for bird, a reference to its pugnacious behaviour and habit of dispossessing other species of their nests. The specific name comes from the Latin rixosus meaning quarrelsome, again referring to the behaviour and temperament of the species.
The species has a disjunct distribution, with three subspecies accepted: Wikipedia →

GBIF citizen-science records
It is estimated from how often the Cattle Tyrant is recorded against all the birds logged in Montevideo (800 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
