The scarlet-rumped cacique (Cacicus uropygialis) is a passerine bird species in the New World blackbird family Icteridae. This species has sometimes been split into two species: the scarlet-rumped cacique (Cacicus microrhynchus) and the subtropical cacique (Cacicus uropygialis).
The scarlet-rumped cacique was formally described in 1843 by the French ornithologist Frédéric de Lafresnaye based on a specimen collected in Colombia. He coined the binomial name Cassicus uropygialis where the specific epithet is from Medieval Latin uropygium meaning "rump". The scarlet-rumped cacique is now one of ten species placed in the genus Cacicus that was introduced in 1799 by the French naturalist Bernard Germain de Lacépède.
Three subspecies are recognised: Cacicus uropygialis microrhynchus (Sclater, PL & Salvin, O, 1865) – far northeastern Honduras to eastern Panama (except Darién Province) Cacicus uropygialis pacificus Chapman, FM, 1915 – eastern Panama (Darién Province) to western Colombia and western Ecuador (El Oro)

With luck
About 10% of wildlife watchers report a Scarlet-rumped Cacique sighting in Chagres National Park on a given day, based on 110 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 134th most-seen of the 372 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
February
In that month about 20% of wildlife watchers report a Scarlet-rumped Cacique in Chagres National Park on a given day, against under 5% in September–October and December, the lowest months. That is one of Chagres National Park's driest months, with about 30 mm of rain against 300 mm in July.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Scarlet-rumped 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.
11th of 22
Of the 22 parks where we can rate Scarlet-rumped Cacique sightings, Chagres National Park ranks 11th at about 10%. The best odds are in Soberanía National Park (Panama, about 40%), Piedras Blancas National Park (Costa Rica, about 40%) and Utría National Natural Park (Colombia, about 30%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Scarlet-rumped Cacique is recorded against all the birds logged in Chagres National Park (110 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.
