The sulphur-bellied flycatcher (Myiodynastes luteiventris) is a large member of the family Tyrannidae, the tyrant flycatchers. It is regularly found from southern Arizona in the United States south to Bolivia and occurs casually or as a vagrant further north, east, and south of its usual range.
The sulphur-bellied flycatcher is monotypic. Because there is much clinal variation in size and plumage, several subspecies have been proposed but not accepted. The sulphur-bellied flycatcher and the streaked flycatcher (M. maculatus) are sister species.
The sulphur-bellied flycatcher is about 20 cm (7.9 in) long and weighs about 40 to 57 g (1.4 to 2.0 oz). The sexes have the same plumage. Adults have a pale hoary gray or grayish white forecrown and supercilium. They have a brownish gray to olive crown with blackish streaks and a large, usually hidden, canary-yellow patch in the center. They have dusky lores; the color extends to the ear coverts and forms a dark "mask". Below the mask is a wide white stripe with thin dusky streaks and below that a thin dusky stripe. Their nape and upperparts to the upper rump are light olive with a buffy tinge... Wikipedia →

Rare
Under 5% of wildlife watchers report a Sulphur-bellied Flycatcher sighting in Cahuita National Park on a given day, based on 33 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 192nd most-seen of the 303 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
September and October
In those months about 10% of wildlife watchers report a Sulphur-bellied Flycatcher in Cahuita National Park on a given day, against under 5% in November to August, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Sulphur-bellied Flycatcher sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

GBIF citizen-science records
It is estimated from how often the Sulphur-bellied Flycatcher is recorded against all the birds logged in Cahuita National Park (33 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.
