Olive-chested Flycatcher

The olive-chested flycatcher is about 12 cm (4.7 in) long and weighs about 8.5 to 11 g (0.30 to 0.39 oz). The sexes have almost identical plumage. Adult males have a dull olive-brown crown with a partially hidden yellow patch in the middle. Females have a smaller patch than males. Both sexes have dark lores, a whitish line over them, and a thin whitish broken eye-ring on an otherwise dark olive face. Their back and rump are dark olive. Their wings are dusky with whitish buff tips of the wing coverts that show as two wing bars. Their tail is dusky. Their throat is dirty white. Voice: The olive-chested flycatcher's song is "an evenly spaced series of rich dewp or wheep notes sometimes interspersed with chattered phrases: dji'dji'dji-wheep dji'dji'dji-wheep dji'dji'dji-wheep". Its call is "a rapid, rich, rising errr'djidjidjidjidjidjidji?". Other descriptions are "an endlessly repeated 'chwee...whwee...chwee...' " song and "a sprightly 'weee d'd'd'd'd'd'd?' " call.
