The silvery-throated jay was originally described in 1875 as Cyanocitta angentigula. It was later reassigned to its present genus Cyanolyca that had been erected in 1851.

Their upper back is black and their lower back, scapulars, rump, and uppertail coverts are dusky purplish blue. Their wings and tail are blue. Their throat and upper breast are pale lavender or silvery white. They have a black band across the lower breast that becomes dusky purplish blue on the belly and undertail coverts.

GBIF citizen-science records
It is estimated from how often the Silvery-throated Jay is recorded against all the birds logged in Volcán Barú National Park (19 verified sightings from 2019 to 2026), 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.
