The blackish-blue seedeater (Amaurospiza moesta) is a species of bird in the family Cardinalidae, the cardinals or cardinal grosbeaks. It is found in Argentina, Brazil, and Paraguay. The blackish-blue seedeater is monotypic.
It and the other members of genus Amaurospiza were traditionally placed in family Emberizidae. (At that time, the family included the New World sparrows, which are now in their own family Passerellidae.) Since approximately 2008 they have been placed in their current family.
The blackish-blue seedeater is 12 to 12.5 cm (4.7 to 4.9 in) long and weighs 12.5 to 14 g (0.44 to 0.49 oz). The male is entirely dark slaty blue that is darker on the face and underparts. The female is tawny brown, with the underparts paler than the upperparts.
The blackish-blue seedeater is primarily found in southeastern Brazil and adjoining eastern Paraguay and northeastern Argentina. However, there are also scattered records further north in Brazil. It inhabits the undergrowth and edges of woodland and is especially partial to Chusquea and Guadua bamboo. In elevation it ranges from sea level to 1,600 m (5,200... Wikipedia →

Rare
Under 5% of wildlife watchers report a Blackish-blue Seedeater sighting in Iguaçu National Park on a given day, based on 82 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 205th most-seen of the 346 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
In every month with enough records, under 5% of wildlife watchers report a Blackish-blue Seedeater in Iguaçu National Park on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Blackish-blue Seedeater sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 3 parks where we can rate Blackish-blue Seedeater sightings, Iguaçu National Park ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Iguazú National Park (Argentina, under 5%).
GBIF citizen-science records
It is estimated from how often the Blackish-blue Seedeater is recorded against all the birds logged in Iguaçu National Park (82 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.
