Fluvicolinae

Fluvicolinae is a subfamily of passerine birds in the tyrant flycatcher family Tyrannidae, encompassing species widely distributed across the Americas. The subfamily includes 130 species that are divided into five tribes and 39 genera.

== Taxonomy == Broad studies in molecular genetics performed by Tello et al. (2009) discovered a large number of new relationships within the family Tyrannidae that were not reflected in the majority of species classified as part of the family. Following these studies, Ohlson et al. (2013) proposed a reorganization and division of the family Tyrannidae, which according to the proposal would divide the family into the subfamilies Fluvicolinae, Hirundineinae Tello, Moyle, Marchese & Cracraft, 2009, Muscigrallinae Ohlson, Irestedt, Ericson & Fjeldså, 2013, Tyranninae Vigors, 1825 and Elaeniinae, Cabanis & Heine, 1859–60.
