Cinnamon Flycatcher
Pyrrhomyias cinnamomeus
The cinnamon flycatcher is 11 to 13 cm (4.3 to 5.1 in) long and weighs about 11 g (0.39 oz). The sexes have the same plumage. Adults of the nominate subspecies P. c. cinnamomeus have a dark brownish crown with a partially hidden yellow patch in the center. They have a faint buffy eye-ring and patch above the lores, olive-brown cheeks and nape, and cinnamon-rufous sides of the neck. Their upperparts are olive-brown with a thin, often hidden, cinnamon-orange band on the rump. Voice: The cinnamon flycatcher does not have a dawn song. Its calls include a "dull, low-pitched...rattle, pti-i-i-i-i, spit out rather abruptly", a "stuttering pit, pti-pit-it", and "a few chip, tsip and pit notes". Another description of its main call is "a low-pitched dry rattling tr-r-r-r-r-r or dr-r-r-r-r-r".

Yellow-crowned Tyrannulet
Tyrannulus elatus
The yellow-crowned tyrannulet is 10 to 11 cm (3.9 to 4.3 in) long and weighs 6.5 to 8 g (0.23 to 0.28 oz). Adult males have a slate-gray to dark brown or blackish crown with a bright yellow to orange-yellow stripe along its middle. Their nape and back are bright olive-green. They have a grayish supercilium, a thin dark line through the eye, and a pale gray lower face. Their wings are dusky with two white to yellowish white bars. Their tail is dusky olive. Their throat is pale gray and their underparts pale to medium yellow with an olive wash on the breast. Voice: The yellow-crowned tyrannulet's song is a "2-noted, clear, plaintive 'wih-weér' (or 'free beer'), 2nd note higher, shorter, and stressed". It apparently differs little across the species' range.
