bird was formerly considered to belong to the same species as the western
Bullock's Oriole, under the combined name of "Northern Oriole".
South Dakota birds can be variously intermediate between the two species, as
they interbreed where their ranges come into contact. A male
is pictured on the right, while links to female Baltimore Orioles can be found
at the bottom of the page.
Habitat: Woodlands, riverside groves,
Diet: Insects, berries, and nectar. In summer, primarily insects. Eats
many berries and sometimes cultivated fruit
Behavior: Forages by moving through the foliage of
trees and shrubs in search of insects. Will also go take nectar from
Nesting: Mid-May through August in South Dakota.
The nest is a large hanging bag-shaped pouch of grasses, vines, string, bark
strips, or other linear, thin material. The female lays 4 or 5 eggs, with
the female alone incubating them. After the eggs hatch, both parents help
to feed the nestlings, who leave the nest after about 2 weeks.

Migration: Neotropical migrant, although some may
winter in the Southeastern U.S. Generally migrates quite early in the

comparison between the two. Elsewhere in parts of their normal range, could be
confused with the Hooded Oriole or Altamira
Bird Feeders: Oranges, peanut butter and suet,
sometimes sugar water/nectar. Specialized "oriole feeders" are sold which
help birders offer fruit, jelly, or nectar to oriole species.
