Research Paper On Tyrant Flycatchers

Tyrant flycatchers constitute a substantial component of the land bird fauna in all South American habitats (Ohlson, J., Fjeldså J. & Ericson). Tyrannidae consists of two main lineages. An expanded pipromorphine clade includes flatbills, tody-tyrants and antpipits, and also Phylloscartes and Pogonotriccus. Tyrant flycatchers form a well-supported clade, subdivided in two large subclades, which differ consistently in foraging behaviour, the perch-gleaning elaeniines and the sallying tyrannines and fluvicolines.
Tyrannida took place in a humid forest environment during the Oligocene. Large-scale diversification in open habitats is confined to the clade consisting of the elaeniines, myiarchines, tyrannines and fluvicolines. Tyrannine–fluvicoline
