Readily adapts to some suburban neighborhoods if enough trees are present. Winters mostly in the tropics around forest edge and semi-open country.

Juveniles are similar to females, but are paler overall and lack the black coloration on the head and upper plumage. Juvenile males have a brighter orange with variable amounts of black on head. In the second year, the males still have not attained their adult plumage, yet may successfully attract and mate with a female and raise young.

Juvenile males will attain adult plumage in the second fall. However, the male Baltimore Orioles can easily be differentiated by their entirely black head. Also, the plumage of Orchard Oriole males is a darker, brick-red coloration. The Bullock's Orioles may be differentiated from Baltimore Orioles by the orange face and black eye lines.

The female can be differentiated from the female Bullock Oriole by her more orange chest and less grey upper plumage. The Hooded and Orchard Orioles have a more extensively yellow under plumage.

Baltimore Orioles feed on berries, flower nectar, various soft fruits and insects, including caterpillars. They typically forage in trees and shrubs, but also make short flights to catch insects in midair.

In South America they often feed in flowering trees Ridgely and Tudor They are often seen feeding at hummingbird feeders. Oriole feeders are similar to hummingbird feeders, except they are orange instead of red and have larger perches since orioles perch while feeding, while hummingbirds mostly hover in front of it.

Its deep, tightly woven pouch nest is usually situated in the canopy of hardwood trees, about feet meters above the ground.

The nest is typically hanging down from the tip of a drooping branch. It is constructed of plant fibers, grasses, tree bark and string. The nest is designed to close the opening entrance when weighted, as it would be, for example, when there are chicks in the nest.

Because he is the recognized authority on the subject, we asked him to explain to us at Journey North exact ly why ornithologists used to think Bullock's and Baltimore Orioles were the same species, called the "Northern Oriole," and why they changed their mind.

Rising explains: First things first: What Is a Species? You might ask, "What do you mean by different? Usually it means that they look different. Eastern Bluebirds and American Robins look different, and they are different species.

However, male and female Cardinals also look different, but they are not different species. They are simply different sexes of the same species. So there must be more to it than that. Biologists, therefore, often define a species as a group of individuals who cannot mate with individuals of another group species and produce healthy young that will be able to reproduce when they are adults.

For example, the Hooded Merganser and Common Goldeneye two kinds of ducks sometimes hybridize, but the young that they produce almost certainly cannot breed and produce young. Also matings between these two ducks are very rare. Thus, they are not considered to be the same species.
