Swainson's flycatcher (Myiarchus swainsoni) is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is found in every mainland South American country except Chile and French Guiana and as a vagrant to Aruba and Trinidad.
However, this taxonomy is unsettled. All four subspecies were previously treated as individual species but were combined as one in the 1930s. Studies published in the early 2000s showed that the nominate subspecies M. s. swainsoni differs genetically from the other three, which appear to be more closely related to the dusky-capped flycatcher (M. tuberculifer) than to swainsoni. In light of these studies some authors have urged that further studies be undertaken, and the South American Classification Committee of the American Ornithological Society is seeking a proposal to reevaluate the species. The Clements taxonomy takes a different approach than that suggested by the studies. It treats... Wikipedia →

With luck
About 10% of wildlife watchers report a Swainson's Flycatcher sighting in Emas National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 140th most-seen of the 187 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
June–July and October
In those months about 10% of wildlife watchers report a Swainson's Flycatcher in Emas National Park on a given day, against under 5% in March, May, August–September and November, the lowest months. Those are among Emas National Park's driest months, with about 40 mm of rain a month against 190 mm in January. April and December–February have too few records to rate.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Swainson's 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.
5th of 15
Of the 15 parks where we can rate Swainson's Flycatcher sightings, Emas National Park ranks 5th at about 10%. The best odds are in Iberá National Park (Argentina, about 20%), El Impenetrable National Park (Argentina, about 10%) and El Palmar National Park (Argentina, about 10%).
Same genus: Myiarchus
The closest relatives of the Swainson's Flycatcher that you can see in Emas National Park (genus Myiarchus, Myiarchus Flycatchers) are Short-crested Flycatcher (about 20%) and Brown-crested Flycatcher (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Swainson's Flycatcher is recorded against all the birds logged in Emas National Park (11 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.
