The lesser wagtail-tyrant (Stigmatura napensis) is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is found in Brazil, Colombia, Ecuador, Peru, and Venezuela. What is now the lesser wagtail-tyrant was originally described as Stigmatura budytoides napensis, a subspecies of the greater wagtail-tyrant. What is now the Bahia wagtail-tyrant (S. bahiae) was described as another subspecies at the same time. They were later treated as two subspecies of the lesser wagtail-tyrant. BirdLife International's Handbook of the Birds of the World separated them from each other as monotypic species in 2014. The Clements taxonomy did so in late 2022 and the International Ornithological Committee in early 2023. As of late 2024 the South American Classification Committee of the American Ornithological Society had not adopted the split. A population in the upper Orinoco Basin that is separate from the rest of the species is suspected of being a subspecies or possibly a species.
The lesser wagtail-tyrant is 13 cm (5.1 in) long. The sexes have the same plumage; males are slightly larger than females. Adults have a thin pale yellow supercilium... Wikipedia →

Rare
Under 5% of wildlife watchers report a Lesser Wagtail-Tyrant sighting in Yasuní National Park on a given day, based on 25 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 448th most-seen of the 533 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 Lesser Wagtail-Tyrant in Yasuní National Park on a given day, so our monthly data shows no clear season.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Lesser Wagtail-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.
Yes
Of the 2 parks where we can rate Lesser Wagtail-Tyrant sightings, Yasuní National Park has the highest daily chance: under 5%. Next come Amacayacu National Natural Park (Colombia, under 5%).

GBIF citizen-science records
It is estimated from how often the Lesser Wagtail-Tyrant is recorded against all the birds logged in Yasuní National Park (25 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.
