The lesser shrike-tyrant (Agriornis murinus) is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is found in Argentina, Bolivia and Paraguay and as a vagrant to Brazil, Chile, and Uruguay. The lesser shrike-tyrant was formally described in 1837 as Pepoazae murina. For much of the twentieth century it was placed in genus Xolmis but by the 1980s most authors had transferred to genus Agriornis that was erected in 1839.
The lesser shrike-tyrant is monotypic. The lesser shrike-tyrant is 16 to 18.5 cm (6.3 to 7.3 in) long. Adult males have a gray-brown crown, mottled blackish and white lores, and a whitish or buffy supercilium and eye-ring. Their upperparts are gray-brown. Their wings are mostly dusky with whitish tips on the coverts and whitish edges on the inner flight feathers. Their tail is mostly dusky with pale grayish to white outer webs on the outermost pair pair of feathers. Their throat is white with thin black streaks, their breast very pale grayish brown, their flanks pale grayish brown with a buff tinge, and their belly creamy whitish. Adult females have almost the same plumage but the streaks on their throat... Wikipedia →

Rare
Under 5% of wildlife watchers report a Lesser Shrike-Tyrant sighting in Cordoba on a given day, based on 19 verified sightings from GBIF citizen-science data. It is the 142nd most-seen of the 176 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Lesser Shrike-Tyrant in Cordoba on a given day, so our monthly data shows no clear season.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Lesser 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 Cordoba, in our data
Cordoba is the only city on Wallace's Line with enough records to rate Lesser 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 Lesser Shrike-Tyrant is recorded against all the birds logged in Cordoba (19 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.
