About the Sulphur-bellied Flycatcher

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 →
