The violet-capped woodnymph (Thalurania glaucopis) is a species of hummingbird in the "emeralds", tribe Trochilini of subfamily Trochilinae. It is found in Argentina, Brazil, Paraguay, and Uruguay. The violet-capped woodnymph was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with all the other hummingbirds in the genus Trochilus and coined the binomial name Trochilus glaucopis. Gmelin based his description on "L'oiseau-mouche à queue fourchue du Brésil" that had been described and illustrated in 1760 by the French zoologist Mathurin Jacques Brisson from a preserved specimen that had been sent to Paris from Brazil. The violet-capped woodnymph is now placed with three other woodnymphs in the genus Thalurania that was introduced in 1848 by the English ornithologist John Gould. The genus name combines the Ancient Greek thalos meaning "child" with ouranos meaning "heaven". The specific epithet glaucopis is from the Ancient Greek glaukos meaning "blue-grey" or "glaucous" with ōps meaning "face". The species is treated as monotypic: no subspecies... Wikipedia →

Rare
Under 5% of wildlife watchers report a Violet-capped Woodnymph sighting in São Paulo on a given day, based on 374 verified sightings from GBIF citizen-science data. It is the 123rd most-seen of the 353 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.
July
In that month about 10% of wildlife watchers report a Violet-capped Woodnymph in São Paulo on a given day, against under 5% in August to June, the lowest months. That is one of São Paulo's driest months, with about 60 mm of rain against 230 mm in January.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Violet-capped Woodnymph sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 7
Of the 7 cities where we can rate Violet-capped Woodnymph sightings, São Paulo ranks 4th at under 5%. The best odds are in Rio de Janeiro (Brazil, about 20%), Santos (Brazil, about 10%) and Curitiba (Brazil, under 5%).
GBIF citizen-science records
It is estimated from how often the Violet-capped Woodnymph is recorded against all the birds logged in São Paulo (374 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.
