The little ground tyrant (Syrtidicola fluviatilis) is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is found in Bolivia, Brazil, Peru, possibly in Colombia, and as a vagrant in Ecuador. The little ground tyrant was originally described as Muscisaxicola fluviatilis. A genetic study published in 2020 found that it was deeply divergent from other members of Muscisaxicola and was instead sister to the yellow-browed tyrant (Satrapa icterophrys). During 2021 the South American Classification Committee of the American Ornithological Society (SACC), the IOC, and the Clements taxonomy therefore moved the little ground tyrant to the newly erected genus Syrtidicola. However, as of December 2024 BirdLife International's Handbook of the Birds of the World retains the species in genus Muscisaxicola.
The little ground tyrant is the only member of genus Syrtidicola and has no subspecies. The little ground tyrant is 13 to 14 cm (5.1 to 5.5 in) long. The sexes have the same plumage. Adults have a pale buffy supercilium and line above their lores. The rest of their face and their crown, nape, and back are grayish sandy brown. Their... Wikipedia →

Rare
Under 5% of wildlife watchers report a Little Ground-Tyrant sighting in Tambopata National Reserve on a given day, based on 45 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 395th most-seen of the 550 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 Little Ground-Tyrant in Tambopata National Reserve on a given day, so our monthly data shows no clear season.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Little Ground-Tyrant sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 3 parks where we can rate Little Ground-Tyrant sightings, Tambopata National Reserve ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Manu National Park (Peru, under 5%).
Same family: Tyrannidae
The closest relatives of the Little Ground-Tyrant that you can see in Tambopata National Reserve (family Tyrannidae, Tyrant Flycatchers) are Tropical Kingbird (about 20%), Boat-billed Flycatcher (about 20%) and Forest Elaenia (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Little Ground-Tyrant is recorded against all the birds logged in Tambopata National Reserve (45 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.
