Black-and-white Tody-Flycatcher

The black-and-white tody-flycatcher is about 9 to 9.5 cm (3.5 to 3.7 in) long and weighs 5.6 to 8 g (0.20 to 0.28 oz). Adult males have an almost entirely glossy black head and upperparts. They have a small white spot above their lores, a white eye-ring, and wide pale yellow edges on their tertials. Their throat and underparts are mostly white, with streaky black on the sides of the breast that sometimes extends in a thin band across the breast, and a pale yellow tinge on the flanks and crissum. Females have a chestnut crown and buffy lores and eye-ring on an otherwise mostly gray face. Voice: The black-and-white tody-flycatcher's call is a "fast sharp 'tik, t-r-r-r-r-r-r-ew' ", and when agitated it give a "more explosive 'tk, tk, tk, whey-whey-whey-whuh' ".
