Tyranni (suboscines) is a clade of passerine birds that includes more than 1,000 species, the large majority of which are South American. It is named after the type genus Tyrannus.
These have a different anatomy of the syrinx musculature than the oscines (songbirds of the larger suborder Passeri), hence its common name of sub-oscines. The available morphological, DNA sequence, and biogeographical data, as well as the (scant) fossil record, agrees that these two major passerine suborders are evolutionarily distinct clades.
According to Sibley and Ahlquist's DNA-DNA hybridization studies the Tyranni can be divided into three infraorders: Acanthisittides, Eurylaimides, and Tyrannides. The first, containing the Acanthisittidae (New Zealand "wrens"), is of disputed position. Current opinion is that they are more likely a very distinct and ancient lineage, and constitute a suborder on their own.
The Eurylaimides contain the Old World suboscines – mainly distributed in tropical regions around the Indian Ocean – and a single American species, the broad-billed sapayoa:
