The jet antbird is monotypic. The jet antbird is 14 to 15.5 cm (5.5 to 6.1 in) long and weighs 15 to 17.5 g (0.53 to 0.62 oz).

Only Cali, in our data
Cali is the only city on Wallace's Line with enough records to rate Jet Antbird sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Jet Antbird is recorded against all the birds logged in Cali (145 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.
