White-bellied Tody-Tyrant

The white-bellied tody-tyrant is 9.5 to 11 cm (3.7 to 4.3 in) long and weighs 8 to 10 g (0.28 to 0.35 oz). The sexes and the subspecies have essentially the same plumage. Adults have an olive-green crown and nape. They have gray lores, an indistinct white eye-ring, and light gray ear coverts. Their back and rump are olive-green. Their wings are dusky with pale yellow edges on the flight feathers and pale yellow tips on the coverts; the latter show as two distinct wing bars. Their tail is olive-green. Voice: The white-bellied tody-tyrant makes a variety of tik vocalizations, sometimes singly and sometimes combined as in tu-rik or in a sequence. A description of its song is "a simple chiming pair or trio of notes, the first lower: ta-TEEK or ta-TI'PIP".
