Black-throated Tody-Tyrant
Hemitriccus granadensis
The black-throated tody-tyrant is 8.5 to 11 cm (3.3 to 4.3 in) long and weighs 6.5 to 8.5 g (0.23 to 0.30 oz). The sexes have the same plumage. Adults of the nominate subspecies H. g. granadensis have a dark olive crown. Their lores and wide eye-ring are whitish and their ear coverts grayish olive. Their back and rump are dark olive. Their wings are dark olive with indistinct yellow edges on the coverts. Their tail is dark dusky olive. Their upper throat and lower cheeks are sooty black and their lower throat whitish with grayish edges. Voice: As of early 2025 xeno-canto had many recordings of black-throated tody-tyrant vocalizations from Colombia, Ecuador, and Peru but only one from Bolivia and none from Venezuela. The nominate subspecies gives a "short rattling trill, 'ti-ti-r-r-r-r-r-r'" or a "fast trill". Other calls include "a gravelly 'dut't't, dut't't', a nasal 'tip-buuuuu' and sharp 'pik, peet, peet' ".

Pearly-vented Tody-Tyrant
Hemitriccus margaritaceiventer
The pearly-vented tody-tyrant is about 10 to 11 cm (3.9 to 4.3 in) long and weighs 7 to 10 g (0.25 to 0.35 oz). The sexes have the same plumage. Adults of the nominate subspecies H. m. margaritaceiventer have a gray crown. Their lores and eye-ring are whitish on an otherwise grayish brown face. Their back and rump are drab grayish brown to brownish olive. Their wings are dusky with buff whitish to yellow edges on the flight feathers and tips of the coverts; the latter show as two wing bars. Their tail is dusky. Their throat and underparts are white with some faint grayish streaking. Voice: Though recordings of some subspecies are lacking, the pearly-vented tody-tyrant's vocalizations appear to be similar across its range. Its song has been described as a "modest, soft yet emphasized series...'tuc-tic-tuc-tuc-tuc-tuc' ". Other descriptions are "tip...tip...tiptrrtrrrrr", "tup tchup tchip ti-teeeeeerrrr", and "stick, tic-tic-ter'r'r'r'r'r'r'r'r'r'r".
