These birds are unique in their ability to manipulate their vocal tract to produce melodic and complex songs. Some of the synonyms for suborder Oscines include passeriformes, Acanthomorphae, and percomorphs. Passeriformes, meaning "sparrow-like," represents the largest order of birds and includes over half of all bird species. Acanthomorphae refers to a group of fish-like birds, while percomorphs describe a group of perch-like birds.
