The ultramarine grosbeak (Cyanoloxia brissonii) is a species of grosbeak in the family Cardinalidae. It is found in a wide range of semi-open habitats in eastern and central South America, with a disjunct population in northern South America.
These birds are 15 cm long. Adult males exhibit a dark-blue plumage with bright-blue highlights on the head and upper-wings and black on the face, wings and tail. The females and the juveniles are brown. Both sexes show black legs and large, thick bill.
The Ultramarine Grosbeak is sedentary, only noted to have short-distance local migrations. Individuals of this species are solitary and often territorial, rarely associating with conspecifics or loosely aggregating in mixed-species flocks.
Ultramarine Grosbeaks occur in open or semi-open edge habitats, in dense scrub such as thickets, preferably at the edge of swamps, secondary forests, and agricultural fields or plantations. The distribution of these birds is disjunct; their range extends from northeast and central Brazil to Bolivia, Paraguay, and Argentina and throughout the Gran Chaco. An isolated population can be found in southwestern Colombia... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Ultramarine Grosbeak is recorded against all the birds logged in Rosario (6 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.
