The white-vented violetear (Colibri serrirostris) is a species of hummingbird in the subfamily Polytminae, the mangoes. It is found in Argentina, Bolivia, Brazil, and Paraguay. In April, 2024, one was also photographed at Batsu Gardens in Costa Rica.
The white-vented violetear is monotypic. The white-vented violetear is 12 to 13 cm (4.7 to 5.1 in) long and weighs 5.6 to 6.8 g (0.20 to 0.24 oz). The male is mostly shiny green, of a shade lighter than that of other violetears. Towards the rump it is yellow-green with a blue shimmer. The tail is glittering green with a wide steel-blue band near the end. The undertail coverts are pure white. The area behind the eye and covering the ears is violet blue. The female is similar to the male but paler and more grayish. The maxilla of both sexes is sometimes serrated, which provides its specific epithet.
The white-vented violetear is found in a wide swath of southern Brazil, from Mato Grosso east to Goiás, Bahia and Espírito Santo and south to Santa Catarina. Its range extends west into Bolivia, central Paraguay, and northern Argentina as far south as Córdoba Province... Wikipedia →

It is the 162nd most-seen of the 247 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.
Any time of year

GBIF citizen-science records
It is estimated from how often the White-vented Violetear is recorded against all the birds logged in Curitiba (32 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.
