Todd's Antwren

Todd's antwren is 10 to 11 cm (3.9 to 4.3 in) long and weighs 8 to 9.5 g (0.28 to 0.34 oz). Adult males have a black forehead with short white streaks, a black crown and nape, a long white supercilium, and a black streak behind the eye. Their back and rump are light gray with small black patches, white-edged black scapulars, and a white patch between the scapulars. Their wings are black with white tips on the coverts and white edges on the flight feathers. Their tail is black; the feathers have white tips, white spots and a white streak on the central ones, and white edges on the outer ones. Voice: The song of Todd's antwren is a "short, high, rapid series of about 12 notes, which descend and slow down at the end". Its calls include an "abrupt, downslurred 'tup' and even more abrupt, vibrant 'chit' ". Its song is the easiest way to separate it from the spot-tailed antwren, as both are hard to see in the forest canopy.
