The blue dacnis or turquoise honeycreeper (Dacnis cayana) is a small passerine bird in the family Thraupidae, the tanagers and allies. It is found in Central America from Honduras to Panama, on Trinidad, and in every mainland South American country except Chile and Uruguay.
In 1760, the French zoologist Mathurin Jacques Brisson included a description of the blue dacnis in his Ornithologie based on a specimen collected in "Cayenne" (French Guiana). He used the French name Le Pepit bleu de Cayenne and the Latin name Sylvia cayanensis caerulea. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognized by the International Commission on Zoological Nomenclature. When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition he added 240 species that had been previously described by Brisson. One of these was the blue dacnis. Linnaeus included a terse description, coined the binomial Motacilla cayana and cited Brisson's work. The specific epithet cayana is from Cayenne. This species is now placed in the genus Dacnis that was introduced in 1816 by the French naturalist Georges Cuvier with the... Wikipedia →

Rare
Under 5% of wildlife watchers report a Blue Dacnis sighting in Poás Volcano National Park on a given day, based on 36 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 203rd most-seen of the 356 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Blue Dacnis in Poás Volcano National Park on a given day, so our monthly data shows no clear season.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Blue Dacnis sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
40th of 44
Of the 44 parks where we can rate Blue Dacnis sightings, Poás Volcano National Park ranks 40th at under 5%. The best odds are in Serra dos Órgãos National Park (Brazil, about 60%), Chapada Diamantina National Park (Brazil, about 50%) and Itatiaia National Park (Brazil, about 50%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Blue Dacnis is recorded against all the birds logged in Poás Volcano National Park (36 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.
