About the Bullock's Oriole
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 →
