The Baltimore oriole is a small passerine.

Baltimore orioles are known for building their nests with any stringy material that they can find.

Male and female, working together, may use grass or moss to construct a nest. However, they will also use items discarded by human beings, such as ribbons, rubber bands, and threads from old pieces of clothing.

The male Baltimore oriole has a black head and back. His chest, belly and rump are bright orange. His wings are orange with white bars. He has an orange tail with black streaks.
