The Tyranni (suboscines) are a suborder of passerine birds that includes more than 1,000 species, a large majority of which are South American.

These have a different anatomy of the syrinx musculature than the oscines (songbirds of the larger suborder Passeri), hence the common name of suboscines.

The suboscines originated in South America about 50 million years ago[1] and dispersed into the Old World likely via a trans-Atlantic route during the Oligocene.

The cladogram is based on a large molecular genetic study by Carl Oliveros and collaborators published in 2019:[4] The families and the species numbers are from the list maintained by the International Ornithologists' Union (IOC).

In the former case, the name Furnarioidea would be available for the tracheophones, whereas "Tyrannoidea", the "bronchophone" equivalent, has not yet been formally defined.
