The solitary cacique or solitary black cacique (Cacicus solitarius) is a species of bird in the family Icteridae. It is found in Argentina, Bolivia, Brazil, Colombia, Ecuador, Paraguay, Peru, Uruguay, and Venezuela. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical swamps, and heavily degraded former forest. It is a fairly common bird with a very extensive range so the IUCN has rated it as a "species of least concern".
The male solitary cacique has a length of about 27 cm (10.6 in) and the female 23 cm (9.1 in). It differs from all other entirely black birds with dark irises within its range, by having a large white, chisel-shaped, sharply-pointed beak. It could be confused with the Ecuadorian cacique (Cacicus sclateri), but that is smaller and has a restricted range, or the yellow-billed cacique (Amblycercus holosericeus), but that is not found east of the Andes. It has a range of different vocalizations which are mostly delivered at a measured pace but are sometimes interrupted by gurgles and growls.
The solitary cacique has a very wide distribution in Amazonia. Its range extends southwards... Wikipedia →

Rare
Under 5% of wildlife watchers report a Solitary Black Cacique sighting in Manaus on a given day, based on 16 verified sightings from GBIF citizen-science data. It is the 83rd most-seen of the 116 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.
January
In that month about 20% of wildlife watchers report a Solitary Black Cacique in Manaus on a given day, against under 5% in February to November, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Solitary Black Cacique sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
6th of 7
Of the 7 cities where we can rate Solitary Black Cacique sightings, Manaus ranks 6th at under 5%. The best odds are in Maceió (Brazil, about 10%), Buenos Aires (Argentina, about 10%) and Recife (Brazil, about 10%).
GBIF citizen-science records
It is estimated from how often the Solitary Black Cacique is recorded against all the birds logged in Manaus (16 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.
