The white-edged oriole (Icterus graceannae) is a species of bird in the family Icteridae, the oropendolas, New World orioles, and New World blackbirds. It is found in Ecuador and Peru. The white-edged oriole was formally described by John Cassin in 1867 with the binomial Icterus Grace-Annae, which (with modern spelling) remains its binomial. Cassin named it "in honor of my highly esteemed friend, Miss Grace Anna Lewis...accomplished as a teacher of Natural History".
The white-edged oriole is monotypic. The white-edged oriole is 19 to 20 cm (7.5 to 7.9 in) long. Males weigh an average of about 46 g (1.6 oz) and females about 37 g (1.3 oz). The sexes have the same plumage. Adults are mostly orange-yellow. They have black lores, a black "mask", and a black "bib" from the chin to the upper breast. Their back is black. Their wings are mostly black with pale yellow lesser and median coverts. Their innermost secondaries and their tertials have the eponymous wide white edges at their bases that show as a large white patch on the closed wing. Their tail is mostly black with white edges on the outermost pair of feathers and sometimes white tips... Wikipedia →

Rare
Under 5% of wildlife watchers report a White-edged Oriole sighting in Machalilla National Park on a given day, based on 30 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 142nd most-seen of the 248 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.
October and December
In those months about 10% of wildlife watchers report a White-edged Oriole in Machalilla National Park on a given day, against under 5% in January–September and November, the lowest months. Those are among Machalilla National Park's driest months, with about 20 mm of rain a month against 140 mm in February.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most White-edged Oriole sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Machalilla National Park, in our data
Machalilla National Park is the only park on Wallace's Line with enough records to rate White-edged Oriole sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the White-edged Oriole is recorded against all the birds logged in Machalilla National Park (30 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.
