The purple-crowned plovercrest, or violet-crowned plovercrest, (Stephanoxis loddigesii) is a species of hummingbird in the "emeralds", tribe Trochilini of subfamily Trochilinae. It is found in Argentina, Brazil, and Paraguay.
The purple-crowned plovercrest and green-crowned plovercrest (Stephanoxis lalandi) were originally treated as separate species but in the mid-1900s were combined under the name "plovercrest" with the binomial S. lalandi. A study published in 2014 provided evidence that the original two-species treatment was correct. Taxonomists worldwide agreed and the two taxa were restored to species status. They are the only members of the genus and are monotypic.
The purple-crowned plovercrest is 8.5 to 9.5 cm (3.3 to 3.7 in) long. Males weigh about 3.7 g (0.13 oz). Both sexes have a shortish, straight, black bill. Adult males have a shaggy violet-blue crest.

GBIF citizen-science records
It is estimated from how often the Purple-crowned Plovercrest is recorded against all the birds logged in Curitiba (27 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.
