Pale-eyed Pygmy Tyrant
Atalotriccus pilaris
The pale-eyed pygmy tyrant is 8 to 11 cm (3.1 to 4.3 in) long and weighs about 6 g (0.21 oz). The sexes have the same plumage. Adults of the nominate subspecies A. p. pilaris have a bright olive crown and nape that are suffused with grayish. Their lores are whitish above and gray below; they have a pale partial eye-ring and gray ear coverts. Their back, rump, and uppertail coverts are bright olive. Their wings are dusky with olive-green edges on the flight feathers and lemon to pale olive tips on the coverts; the latter show as two wing bars. Their tail is dusky. Voice: The pale-eyed pygmy tyrant's vocalizations are loud for a small bird. One author described its voice as "ry tic notes and rapid nasal trills...often combined, e.g. tic-tttttttttt". Another described it as a "very high, slightly descending, dry 'prruh' trill".

White-ringed Flycatcher
Conopias albovittatus
The white-ringed flycatcher is 15 to 16.5 cm (5.9 to 6.5 in) long and weighs about 24 g (0.85 oz). The sexes have the same plumage; females are slightly smaller than males. Adults of the nominate subspecies have a black to dark sooty brownish crown and face with a mostly hidden lemon-yellow to canary-yellow patch in the center of the crown. They have a white supercilium that begins at the forehead, widens behind the eye, and wraps almost all the way around the nape. Their upperparts vary from grayish olive-green to dark olive or olive-brown. Voice: The white-ringed flycatcher's call is described as very distinctive. It "commences with a long note, followed by rapid, rattling or whirring, repetitive trill, tre-r-r-r-r, tre-r-r-r-r…, kree-ee-ee-eer".
