The fork-tailed flycatcher (Tyrannus savana) is a passerine bird of the tyrant flycatcher family and is a member of a genus typically referred to as kingbirds. Named for the long, forked tail, particularly in males, fork-tailed flycatchers are seen in shrubland, savanna, lightly forested and grassland areas, from southern Mexico to Argentina. They are frequently observed on conspicuous perches whence they sally after insect prey. Northern populations near southern Mexico tend to be permanent residents, while fork-tailed flycatchers that live further south are migrants with a reputation for wandering as far north as New Brunswick, Canada.
The fork-tailed flycatcher was described in 1760 by Mathurin Jacques Brisson under the French name "le tyran à queue fourchue" (lit. 'the fork-tailed tyrant') and then again in 1780 by Georges-Louis Buffon under the name "le savana" (because it lived in savannahs), but it was not until 1802 that François Marie Daudin coined the binomial name Tyrannus savana. The type locality is Suriname.
Four subspecies are recognised: Tyrannus savana monachus Hartlaub, 1844 – southern Mexico to Colombia, the Guianas, and northern Brazil Tyrannus savana... Wikipedia →

Likely
About 40% of wildlife watchers report a Fork-tailed Flycatcher sighting in Emas National Park on a given day, based on 106 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 46th most-seen of the 187 birds we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
October
In that month about 70% of wildlife watchers report a Fork-tailed Flycatcher in Emas National Park on a given day, against about 10% in June, the lowest month. April and December–February have too few records to rate.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Fork-tailed Flycatcher sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 40
Of the 40 parks where we can rate Fork-tailed Flycatcher sightings, Emas National Park ranks 2nd at about 40%. The best odds are in Iberá National Park (Argentina, about 50%). All parks ranked.
Same genus: Tyrannus
The closest relatives of the Fork-tailed Flycatcher that you can see in Emas National Park (genus Tyrannus, Kingbirds) are Tropical Kingbird (about 30%) and White-throated Kingbird (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Fork-tailed Flycatcher is recorded against all the birds logged in Emas National Park (106 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.
