The crowned slaty flycatcher (Empidonomus aurantioatrocristatus) is a species of bird in the family Tyrannidae, the tyrant flycatchers.

The species was for long placed together with the variegated flycatcher in the genus Empidonomus that had been introduced in 1860 by the German ornithologists Jean Cabanis and Ferdinand Heine. In 1984 the American ornithologist Wesley E. Lanyon proposed that the crowned slaty flycatcher should be moved to its own genus Griseotyrannus based on the distinctive syringeal morphology.

Rare
Under 5% of wildlife watchers report a Crowned Slaty Flycatcher sighting in Península Valdés on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 87th most-seen of the 96 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
November
In that month about 10% of wildlife watchers report a Crowned Slaty Flycatcher in Península Valdés on a given day, against under 5% in August–October and December–May, the lowest months. June and July have too few records to rate.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Crowned Slaty Flycatcher sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
9th of 10
Of the 10 parks where we can rate Crowned Slaty Flycatcher sightings, Península Valdés ranks 9th at under 5%. The best odds are in El Impenetrable National Park (Argentina, about 20%), Yasuní National Park (Ecuador, about 10%) and Iberá National Park (Argentina, about 10%).
Same family: Tyrannidae
The closest relatives of the Crowned Slaty Flycatcher that you can see in Península Valdés (family Tyrannidae, Tyrant Flycatchers) are Gray-bellied Shrike-Tyrant (about 20%), Lesser Shrike-Tyrant (about 10%) and Tufted Tit-Tyrant (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Crowned Slaty Flycatcher is recorded against all the birds logged in Península Valdés (9 verified sightings from 2019 to 2026), 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.
