The Baltimore Oriole is one of the few birds in North America that has orange-colored feathers. In addition to the Baltimore Oriole, there are many other interesting varieties of Orioles found all over the world. His tune is made up of a brief string of paired notes that are played anywhere from two to seven times in a row, each time for one to two seconds. The sound is reminiscent of a flute, and it has a full and rich tone. Because the male sings to establish and defend a breeding territory, you won't hear the full song on the wintering grounds because the song is used to establish and defend the territory. Also capable of singing is the female Baltimore Oriole. It's possible that her shorter songs are just her way of communicating with her mate. Duets may be performed by mated pairs on rare occasions.

During territorial disputes, male and female Baltimore Orioles both give a rapid-fire chattering call to one another. There is no specific time of day or year when the chattering can be heard. The alarm call of the Baltimore Oriole is a sharp chucking sound that is repeated over and over again. This call is given by both male and female birds. When the female Baltimore Oriole is defending her nest, she will let out a particularly loud and threatening scream.
