The riverside tyrant's further taxonomy is unsettled. The IOC, the Clements taxonomy, and the South American Classification Committee of the American Ornithological Society assign it these three subspecies: However, BirdLife International's Handbook of the Birds of the World (HBW) treats K. o. sclateri as a separate species, "Sclater's black-tyrant". Clements supports some level of differentiation by calling it the "riverside tyrant (Sclater's)" within the larger species. Some authors suggest that K. o. xinguensis also deserves species status.
This article follows the one-species, three-subspecies model. The riverside tyrant is 15 to 15.5 cm (5.9 to 6.1 in) long and weighs 18 to 21 g (0.63 to 0.74 oz). Adult males of the... Wikipedia →

With luck
About 10% of wildlife watchers report a Riverside Tyrant sighting in Amacayacu National Natural Park on a given day, based on 49 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 201st most-seen of the 436 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.
August
In that month about 20% of wildlife watchers report a Riverside Tyrant in Amacayacu National Natural Park on a given day, against under 5% in January and March–May, the lowest months. That is one of Amacayacu National Natural Park's driest months, with about 160 mm of rain against 390 mm in March.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Riverside Tyrant sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Amacayacu National Natural Park, in our data
Amacayacu National Natural Park is the only park on Wallace's Line with enough records to rate Riverside Tyrant sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Riverside Tyrant is recorded against all the birds logged in Amacayacu National Natural Park (49 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.
