The glaucous-blue grosbeak (Cyanoloxia glaucocaerulea), also known as the indigo grosbeak, is a species of bird in the family Cardinalidae, the cardinals or cardinal grosbeaks. It is found in Brazil, Argentina, Paraguay, and Uruguay.
The glaucous-blue grosbeak is monotypic. For much of its history, the glaucous-blue grosbeak was the only member of genus Cyanoloxia. Following a 2004 publication, the blue-black grosbeak (now Cyanoloxia cyanoides) and ultramarine grosbeak (now Cyanoloxia brissonii) were moved from genus Cyanocompsa. What is now Amazonian grosbeak (Cyanoloxia cyanoides) was later split from blue-black grosbeak.
The glaucous-blue grosbeak is approximately 14 cm (5.5 in) long. Three birds weighed from 16 to 19.5 g (0.56 to 0.69 oz). The male is generally dark sky blue that is lighter on the forehead and rump and is grayish on the lower belly. It has a small black "mask". The female is brown overall, warm and dark above and orange-tinged below. The immature is orange-brown that is darker on the back, and it has a hint of blue on the forehead and cheek.

Possible
About 20% of wildlife watchers report a Glaucous-blue Grosbeak sighting in El Palmar National Park on a given day, based on 107 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 63rd most-seen of the 151 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.

In those months about 40% of wildlife watchers report a Glaucous-blue Grosbeak in El Palmar National Park on a given day, against about 10% in May–July and September, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Glaucous-blue Grosbeak sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

GBIF citizen-science records
It is estimated from how often the Glaucous-blue Grosbeak is recorded against all the birds logged in El Palmar National Park (107 verified sightings from 2019 to 2026), 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.
