Meet the Bold and Beautiful Bullock’s Oriole
Spot a Bullock's oriole in the western U.S. during breeding season. Learn what the males and females look like and hear their song.
To put it simply, the Bullock’s oriole is a bewitching bird if you’re lucky enough to spot one. “Everybody is excited to see such a charismatic, beautiful species,” says Boaz “Bo” Crees, an avian specialist for both the Montana Natural Heritage Program and Montana Audubon.

Male and Female Bullock’s Orioles
Baltimore and Bullock’s orioles are often confused for one another because of their similar colorings. In both species, males feature black on their heads and backs. A key difference is that Bullock’s orioles “have a black eyeline against an orange cheek, instead of an all-black head,” Bo says.
Female Bullock’s are more muted, with yellowish orange heads and throats, whitish bellies and grayish backs. Both males and females sport large white wing bars and measure about 8 inches long with a 12 inch wingspan.
Scientific Name: Icterus bullockii

Bullock’s Oriole Nesting Habits
This species weaves a bag-like structure in a tree and lays three to seven eggs inside. Pairs use natural fibers to create gourd-shaped houses that dangle up to 25 feet off the ground.
Nest construction can take up to 15 days. Discover how orioles weave their elaborate nests.
What Do Bullock’s Orioles Eat?
Orioles are brought to feeders by familiar fruity fare: orange wedges, grapes, bananas, berries and apples. And at times they’ll also stop at a sugar-water feeder or sample fruit-filled suet. Bullock’s orioles also eat insects. “They have a fairly slender beak that’s a really good tweezer for picking up grubs or getting nectar,” Bo says.
Bullock’s are in the U.S. only during their breeding season. To spot an oriole during migration, set out supper early in spring to increase your chances. The Cornell Lab of Ornithology recommends that you “start putting out food before migrants arrive in your area; if it’s not there when they first canvas your yard, they’ll keep going.”
“Bullock’s orioles nest in our big willow tree every spring. They build a hanging nest and usually raise two chicks. They love grape jelly, and this is a young male (above) that comes by for a treat,” says reader Laura Dent.

Range and Habitat
Baltimore orioles are seen in the eastern United States, while Bullock’s are found throughout much of the West beyond the Great Plains. That said, these two orioles do hybridize on the Great Plains. At one point, they were lumped together under the name northern oriole before being split into two separate species.
During migration, take a nature walk near water if you want to spot these birds. “If you see a cottonwood tree and vibrant orange, you’ve likely got an oriole on your hands,” Bo says, noting that orioles particularly like woodlands near water. Also check sycamores and willows for oriole indications. Those resource-rich trees offer orioles some concealing cover, abundant insects and copious materials for their intricately woven hanging nests.
