Mottle-cheeked Tyrannulet
Phylloscartes ventralis
The mottle-cheeked tyrannulet is about 12 cm (4.7 in) long and weighs about 9 g (0.32 oz). The sexes have the same plumage, and the subspecies also have essentially the same plumage as well. Adults have a short thin whitish supercilium, an indistinct broken whitish eye-ring, a dusky line through the eye, a wide whitish and dusky crescent below the eye, a dusky "moustache", and the eponymous whitish and dusky mottled cheeks. Their crown, nape, back, and rump are dark olive. Their wings are dusky with bright olive-yellow outer webs at the base of the flight feathers. Voice: The mottle-cheeked tyrannulet's song has been described as "a descending, accelerating rattle tchep tik tik-teer'r'r'r' and its call as "weak, sneezy, metallic tchee or tchep notes". Another description of is song is a "very high, mainly level pitched, twittering trill, which starts hesitantly, accelerates, then slows down at the end with some very sharp, very high notes".
