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 →

Rare
Under 5% of wildlife watchers report a Swainson's Flycatcher sighting in Chapada Diamantina National Park on a given day, based on 15 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 203rd most-seen of the 271 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.
January and May
In those months about 10% of wildlife watchers report a Swainson's Flycatcher in Chapada Diamantina National Park on a given day, against under 5% in February–April and June–December, the lowest months.
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.
7th of 15
Of the 15 parks where we can rate Swainson's Flycatcher sightings, Chapada Diamantina National Park ranks 7th at under 5%. 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%).
GBIF citizen-science records
It is estimated from how often the Swainson's Flycatcher is recorded against all the birds logged in Chapada Diamantina National Park (15 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.
