The black-capped flycatcher (Empidonax atriceps) is a very small passerine bird in the family Tyrannidae, the tyrant flycatchers. It is found in Costa Rica and Panama. The black-capped flycatcher is monotypic. 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. Their throat is white and their breast and belly pale buffish cinnamon. They have a dark iris, a black maxilla, an orange-yellow mandible with a dark tip, and blackish legs and feet. Juveniles have a slightly duller black cap than adults with browner upperparts, buffy edges and tips on the wing feathers, and a paler belly. Wikipedia →

Any time of year
In every month with enough records, under 5% of wildlife watchers report a Black-capped Flycatcher in San José on a given day, so our monthly data shows no clear season.

GBIF citizen-science records
It is estimated from how often the Black-capped Flycatcher is recorded against all the birds logged in San José (7 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
