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 →

Possible
About 20% of wildlife watchers report a Blue Dacnis sighting in Fortaleza on a given day, based on 91 verified sightings from GBIF citizen-science data. It is the 45th most-seen of the 129 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
August and October
In those months about 40% of wildlife watchers report a Blue Dacnis in Fortaleza on a given day, against about 10% in July and December–January, the lowest months. Those are among Fortaleza's driest months, with about 10 mm of rain a month against 240 mm in April.
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.
Yes
Of the 17 cities where we can rate Blue Dacnis sightings, Fortaleza has the highest daily chance: about 20%. Next come João Pessoa (Brazil, about 20%) and Campo Grande (Brazil, about 20%).
Same family: Thraupidae
The closest relatives of the Blue Dacnis that you can see in Fortaleza (family Thraupidae, Tanagers and Allies) are Sayaca Tanager (about 80%), Bananaquit (about 70%) and Palm Tanager (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Blue Dacnis is recorded against all the birds logged in Fortaleza (91 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.
