The southern tropical pewee (Contopus cinereus) is a small passerine bird in the family Tyrannidae, the tyrant flycatchers. It is found in Argentina, Bolivia, Brazil, and Paraguay. The southern tropical pewee's taxonomy is unsettled.
The North and South American Classification Committees of the American Ornithological Society treat those subspecies and six others as the tropical pewee with the binomial Contopus cinereus. In 2016 HBW separated three of the subspecies as the two-subspecies southern tropical pewee (C. cinereus) and the monotypic western tropical pewee (C. punensis). In 2022 Clements recognized the southern tropical pewee as a species and the IOC followed suit in 2023.
The southern tropical pewee is 13.5 to 14.5 cm (5.3 to 5.7 in) long and weighs about 10 to 15 g (0.35 to 0.53 oz). The sexes have the same plumage. Adults of the nominate subspecies have a dark... Wikipedia →

Possible
About 20% of wildlife watchers report a Southern Tropical Pewee sighting in Sian Ka'an Biosphere Reserve on a given day, based on 387 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 73rd most-seen of the 288 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.
October
In that month about 30% of wildlife watchers report a Southern Tropical Pewee in Sian Ka'an Biosphere Reserve on a given day, against about 10% in April and July–August, the lowest months. That is one of Sian Ka'an Biosphere Reserve's wettest months, with about 160 mm of rain against 30 mm in March.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Southern Tropical Pewee sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 49 parks where we can rate Southern Tropical Pewee sightings, Sian Ka'an Biosphere Reserve ranks 2nd at about 20%, level with the leaders once rounded. The best odds are in El Triunfo (Mexico, about 20%).
GBIF citizen-science records
It is estimated from how often the Southern Tropical Pewee is recorded against all the birds logged in Sian Ka'an Biosphere Reserve (387 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.
