  Tyranni - Wikipedia, the free encyclopedia
The suborder Tyranni (the suboscines) of passerine birds include about 1,000 fairly primitive species, the large majority of which are South American.
These have a less developed vocal structure than the songbirds in the suborder Passeri, the oscine passerines.
Mitochondrial DNA studies have confirmed that the Tyranni and Passeri suborders are genetically distinct.
