Bullock's oriole (Icterus bullockiorum, also known as Icterus bullockii) is a small New World blackbird. At one time, this species and the Baltimore oriole were considered to be a single species, the northern oriole. This bird is named after William Bullock, an English amateur naturalist.
Bullock's orioles are sexually dimorphic, with males being more brightly colored than females. In addition, adult males tend to be slightly larger and heavier than females. Measurements: Length: 6.7–7.5 inches (17–19 cm)
Weight: 1.0–1.5 ounces (28–43 g) Wingspan: 12.2 inches (31 cm) Adults have a pointed bill with a straight culmen. In adult males, the tail is long, square, and jet black. All exposed skin is black, as are the claws and bill, though the base of the lower mandible lightens to bluish-gray.
Adult males are characterized by contrasting yellow-orange and black plumage, a black throat patch, and a white wing patch on the wing coverts. The underparts, breast, and face are orange or yellow; by contrast, the back, wings, and tail are black. A black line extends from each eye to the black crown. Adult females, by contrast, have gray-brown upperparts, duller yellow on the breast... Wikipedia →

Rare
Under 5% of wildlife watchers report a Bullock's Oriole sighting in New York City on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 163rd most-seen of the 359 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Bullock's Oriole in New York City on a given day, so our monthly data shows no clear season.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Bullock's Oriole sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
12th of 24
Of the 24 cities where we can rate Bullock's Oriole sightings, New York City ranks 12th at under 5%. The best odds are in Guadalajara (México, about 20%), Toluca (México, about 10%) and Puebla (México, about 10%).
GBIF citizen-science records
It is estimated from how often the Bullock's Oriole is recorded against all the birds logged in New York City (7 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.
