Golden-crowned Flycatcher
Myiodynastes chrysocephalus
The golden-crowned flycatcher is 18.5 to 22 cm (7.3 to 8.7 in) long and weighs about 37 to 40 g (1.3 to 1.4 oz). The sexes have the same plumage. Adults have a brownish gray to dusky crown with a usually hidden golden-yellow patch in the center. They have a long white supercilium on an otherwise mostly grayish dusky face. Their upperparts are mostly dull olive with a greenish olive rump and uppertail coverts; the last have cinnamon or buffy edges at their tips. Their wings are dusky with thin rufous to tawny-buff edges on the coverts and flight feathers. Voice: The golden-crowned flycatcher's dawn song is "a loud, squeaky REE'chewee?" and its call a "metallic, slightly squeaky rew-TCHI?".

Sulphur-bellied Flycatcher
Myiodynastes luteiventris
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. Voice: Only male sulphur-bellied flycatchers sing. The song is variously described as a "soft, liquid, almost warbled tre-le-re-re, tre-le-re-re", a "persistently repeated, a soft chu-eer", and a "clipped, slightly liquid phrase: chee-a-leet s-lik or chew-ee ti-lit or doo-ee ti-chu". Its "screech" call has been compared to "the protest of a wagon wheel that needs oiling".
