Fuscous Flycatcher
Cnemotriccus fuscatus
The fuscous flycatcher is 13.5 to 15 cm (5.3 to 5.9 in) long and weighs about 12 g (0.42 oz). The sexes have the same plumage. Adult males of the nominate subspecies C. f. fuscatus have a brown crown with a slight rufescent tinge. They have dusky lores, a whitish line above the lores that continues as a supercilium, and a dusky stripe through the eye. Their upperparts are brown with a slight rufescent tinge. Their wings are dusky with wide buffy ends on the coverts that show as two wing bars. Their inner secondaries have thin buff edges and their tertials have whitish edges. Voice: The fuscous flycatcher's vocalizations vary greatly among the subspecies. In Venezuela subspecies C. f. fuscatior sings "a low-pitched, slightly buzzy jaw-jew-jew-jew jew at dawn a shorter rolling pü-breeer-breeer"; its call is "a short, abrupt feétz-beeu". The song and call are similarly described from Ecuador and Peru. C. f. cabanisi gives "a strong, reedy pfEEO! and pfeeu-pfeeu-pfeea".

White-banded Tyrannulet
Mecocerculus stictopterus
The white-banded tyrannulet is 12.5 to 13 cm (4.9 to 5.1 in) long and weighs 8 to 11 g (0.28 to 0.39 oz). The sexes have the same plumage. Adults of the nominate subspecies have a medium gray crown. They have a white supercilium, a blackish stripe through the eye, and a faint dusky crescent behind the ear coverts on an otherwise whitish face. Their upperparts are dark brownish olive. Their wings are dark dusky with bright yellow to ochraceous edges on the flight feathers. Their wing coverts have wide pure white tips that show as two bars on the closed wing. Their tail is dusky olive. Voice: What is thought to be the white-banded tyrannulet's song is "a rising, wheezy rhzeee?, sometimes followed by a rich chew-bit or a scratchy, thin, rising-falling chatter".
