Black-capped Flycatcher

The black-capped flycatcher is 10 to 12 cm (3.9 to 4.7 in) long and weighs about 9 g (0.32 oz). The sexes are alike. Adults have a black crown with a short crest and a bold white eye-ring that is wider behind the eye on an otherwise brownish olive face. These features by themselves set it apart from all other Empidonax. Their nape and upperparts are also brownish olive. Their tail is dusky with white outer webs on the outer feathers. Their wings are dusky with pale brown edges on the secondaries and tertials. The wing coverts are dusky with pale brown tips that show as two wing bars. Voice: The black-capped flycatcher has a variety of vocalizations. It makes a "loud keep-keer" in the breeding season, a keep-keep-keep-keep during interactions with others of its species, and "simple whistled tsip, chip, or whit" calls.
