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 →

Possible
About 20% of wildlife watchers report a Cattle Tyrant sighting in Goiânia on a given day, based on 104 verified sightings from GBIF citizen-science data. It is the 56th most-seen of the 174 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
February
In that month about 40% of wildlife watchers report a Cattle Tyrant in Goiânia on a given day, against about 10% in March–May, August–September and December, the lowest months. That is one of Goiânia's wettest months, with about 210 mm of rain against almost none in July.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Cattle Tyrant sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
16th of 33
Of the 33 cities where we can rate Cattle Tyrant sightings, Goiânia ranks 16th at about 20%. The best odds are in Rosario (Argentina, about 70%), Buenos Aires (Argentina, about 50%) and Campo Grande (Brazil, about 30%).
Same family: Tyrannidae
The closest relatives of the Cattle Tyrant that you can see in Goiânia (family Tyrannidae, Tyrant Flycatchers) are Great Kiskadee (about 90%), Common Tody-Flycatcher (about 50%) and Tropical Kingbird (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Cattle Tyrant is recorded against all the birds logged in Goiânia (104 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.
