Sclater's tyrannulet (Phyllomyias sclateri) is a species of bird in subfamily Elaeniinae of family Tyrannidae, the tyrant flycatchers. It is found in Argentina, Bolivia, and Peru. In the early to mid twentieth century some authors placed Sclater's tyrannulet in genus Xanthomyias; that genus was merged into Phyllomyias in the 1970s.
The species' common name and specific epithet commemorate the British zoologist Philip Lutley Sclater. Sclater's tyrannulet is 11.5 to 12.5 cm (4.5 to 4.9 in) long. The sexes have the same plumage. Adults of the nominate subspecies have a dull olive-green crown, nape, back, and rump with a grayish tinge on the crown. They have whitish lores and narrow supercilium. Their wings are dusky with pale yellow to whitish edges on the flight feathers and the ends of the coverts; the last show as two bars on the closed wing. Their tail is dusky olive. Their throat is grayish white and their lower face grizzled whitish. Their breast is pale gray that becomes pale yellowish on their flanks and belly. Subspecies... Wikipedia →

Possible
About 20% of wildlife watchers report a Sclater's Tyrannulet sighting in Amboró National Park on a given day, based on 102 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 64th most-seen of the 273 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
September
In that month about 40% of wildlife watchers report a Sclater's Tyrannulet in Amboró National Park on a given day, against about 10% in May, July–August and November, the lowest months. That is one of Amboró National Park's driest months, with about 90 mm of rain against 340 mm in January. June has too few records to rate.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Sclater's Tyrannulet 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 Amboró National Park, in our data
Amboró National Park is the only park on Wallace's Line with enough records to rate Sclater's Tyrannulet sightings: about 20% of wildlife watchers there report one on a given day.
Same family: Tyrannidae
The closest relatives of the Sclater's Tyrannulet that you can see in Amboró National Park (family Tyrannidae, Tyrant Flycatchers) are Black Phoebe (about 60%), Yellow-olive Flycatcher (about 40%) and Sepia-capped Flycatcher (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Sclater's Tyrannulet is recorded against all the birds logged in Amboró National Park (102 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.
