The great shrike-tyrant (Agriornis lividus) is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is found in Argentina and Chile. The great shrike-tyrant was formally described in 1835 as Tamnophilus [sic] lividus.
The great shrike-tyrant is the largest species of tyrant flycatcher, weighing an average of about 99 g (3.5 oz). It is 26 to 28 cm (10 to 11 in) long. The sexes have the same plumage. Adults of the nominate subspecies have a mostly grayish brown head with some whitish on the lores and a cinnamon tinge on the ear coverts. Their upperparts are grayish brown. Their wings are mostly a duskier grayish brown with pale brown edges on the flight feathers. Their tail is mostly black with buffy white tips and edges of the outer webs of the outer feathers. Their throat is white with heavy black streaks. Their underparts are a paler grayish brown than their upperparts, with a cinnamon or cinnamon-buff wash on the lower belly and crissum. Wikipedia →

Rare
Under 5% of wildlife watchers report a Great Shrike-Tyrant sighting in Santiago on a given day, based on 113 verified sightings from GBIF citizen-science data. It is the 59th most-seen of the 110 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
June
In that month about 10% of wildlife watchers report a Great Shrike-Tyrant in Santiago on a given day, against under 5% in July to May, the lowest months. That is one of Santiago's wettest months, with about 65 mm of rain against 5 mm in December.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Great Shrike-Tyrant sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Santiago, in our data
Santiago is the only city on Wallace's Line with enough records to rate Great Shrike-Tyrant sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Great Shrike-Tyrant is recorded against all the birds logged in Santiago (113 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.
