Sirystes

Sirystes is a genus of birds in the tyrant flycatcher family, Tyrannidae. They used to be all considered conspecific. Vocal differences primarily separated the superspecies into four distinct taxa.

The genus contains four species:

 * Western sirystes, Sirystes albogriseus
 * White-rumped sirystes, Sirystes albocinereus
 * Todd's sirystes, Sirystes subcanescens
