When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition, he added 240 species that had been previously described by Brisson. One of these was the oriole blackbird. Linnaeus included a brief description... Wikipedia →

Rare
Under 5% of wildlife watchers report an Oriole Blackbird sighting in Henri Pittier National Park on a given day, based on 17 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 240th most-seen of the 358 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 and March–May
In those months about 10% of wildlife watchers report an Oriole Blackbird in Henri Pittier National Park on a given day, against under 5% in February and June–December, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Oriole Blackbird sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 5
Of the 5 parks where we can rate Oriole Blackbird sightings, Henri Pittier National Park ranks 4th at under 5%. The best odds are in Amacayacu National Natural Park (Colombia, about 20%), Sierra de la Macarena National Park (Colombia, about 10%) and Yasuní National Park (Ecuador, about 10%).
Same family: Icteridae
The closest relatives of the Oriole Blackbird that you can see in Henri Pittier National Park (family Icteridae, New World Blackbirds and Orioles) are Crested Oropendola (about 30%), Russet-backed Oropendola (about 30%) and Carib Grackle (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Oriole Blackbird is recorded against all the birds logged in Henri Pittier National Park (17 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.
