Golden-bellied Flycatcher
Myiodynastes hemichrysus
The golden-bellied flycatcher is 20 to 22 cm (7.9 to 8.7 in) long and weighs about 39 to 42.5 g (1.4 to 1.5 oz). The sexes have the same plumage. Adults of the nominate subspecies M. h. hemichrysus have a thinly black-streaked, dusky grayish olive or dark sooty gray, crown and nape with a large, usually hidden, yellow patch in the center of the crown. They have a wide white supercilium, a wide blackish stripe through the lores and ear coverts, and a grayish olive or dusky cheek with a whitish stripe through it. Voice: The few studies to date have revealed little difference among the vocalizations of the three golden-bellied flycatcher subspecies. The species' dawn song is a "repeated simple phrase kwee!-tee-tu, also transcribed as tree-le-loo, squeeE-yu-drr or PSEE-chirr-rr". Its day song is a "repeated loud strident skeeew! or skeeeuu!".

Streaked Flycatcher
Myiodynastes maculatus
The streaked flycatcher is 20.5 to 23 cm (8.1 to 9.1 in) long and weighs 36.5 to 50 g (1.3 to 1.8 oz). The sexes have the same plumage. Adults of the nominate subspecies M. m. maculatus have an olive to olive-brown crown and nape with thin cinnamon edges on the feathers and a large, partially hidden, bright yellow to orange-yellow patch in the center of the crown. They have black lores; the color extends to the ear coverts and forms a dark "mask". They have a dull white to yellowish white rather blurry supercilium and a white streak below the mask. Voice: The dawn song of northern populations of the streaked flycatcher has variously been described as "cheer-o-wee-wee, right-here-to-me, kawe-teedly-wink, wheeé-cheederee-wheeé, or as a rising note followed by a short musical chatter: reEET-chewlew'put".
