   Note: The true flycatchers of the Old World are Oscines, and
         belong to the family {Muscicapidae}, as the spotted
         flycatcher ({Muscicapa grisola}). The American
         flycatchers, or tyrant flycatchers, are Clamatores, and
         belong to the family {Tyrannidae}, as the kingbird,
         pewee, crested flycatcher ({Myiarchus crinitus}), and
         the vermilion flycatcher or churinche ({Pyrocephalus  rubineus}). Certain American flycatching warblers of
         the family {Sylvicolidae} are also called
         flycatchers, as the Canadian flycatcher ({Sylvania  Canadensis}), and the hooded flycatcher ({S. mitrata}).
         See {Tyrant flycatcher}.
