The silvery-throated jay (Cyanolyca argentigula) is a species of bird in the family Corvidae, the crows and jays. It is found in Costa Rica and Panama. 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.
The silvery-throated jay is 25 to 27 cm (9.8 to 11 in) long and weighs an average of 65 g (2.3 oz). The sexes have the same plumage. Adults of the nominate subspecies have a mostly black head with a pale grayish lavender or silvery white band on the forecrown and rearward as a supercilium to the back of the ear coverts. 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. Subspecies C. a. albior has a pure glossy white forecrown... Wikipedia →

Rare
Under 5% of wildlife watchers report a Silvery-throated Jay sighting in Chirripó National Park on a given day, based on 54 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 199th most-seen of the 332 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
May and August
In those months about 10% of wildlife watchers report a Silvery-throated Jay in Chirripó National Park on a given day, against under 5% in June–July and September–April, the lowest months.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Silvery-throated Jay sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 5 parks where we can rate Silvery-throated Jay sightings, Chirripó National Park has the highest daily chance: under 5%. Next come Volcán Barú National Park (Panama, under 5%) and Los Quetzales National Park (Costa Rica, under 5%).
GBIF citizen-science records
It is estimated from how often the Silvery-throated Jay is recorded against all the birds logged in Chirripó National Park (54 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.
