The pygmy tyrants of South America are tiny flycatchers that feed this way.

The pygmy tyrants are a bird genus, Myiornis, in the Tyrannidae family.

The Pygmy Tyrant is widespread throughout most of the Amazon in northern and central South America.

Among both the family and the order, only the closely related Black-capped Pygmy Tyrant approaches similarly diminutive sizes.

The Black-capped Pygmy Tyrant can be seen alone, in pairs, or family groups, hunting small insects in rapid dashes.

The Short-tailed Pygmy Tyrant prefers to take prey by hover-gleaning from beneath leaves at mid-level in the forest.

The Short-tailed Pygmy Tyrant is truly a pygmy of a bird, with only a handful of the most lilliputian hummingbirds measuring smaller.

The Short-tailed Pygmy Tyrant (Myiornis ecaudatus) is not only the smallest member of the tyrant-flycatcher family, but also the smallest passerine on earth.

The newly established relative, which Dr. Bakker and his colleagues have formally designated as Nanotyrannus ("pygmy tyrant") lancensis, would have been about 17 feet long and weighed 1,000 pounds.

In general, the vocalizations of the Short-tailed Pygmy Tyrant are all unlikely to be recognized as bird vocalizations, but are rather more like the sounds made by crickets or small frogs.

A conference was held at the Burpee museum in 2005, during which paleontologists debated whether these "pygmy tyrants" represented adult specimens of a small species, or juvenile specimens of Tyrannosaurus rex.

The smallest family members are the closely related Short-tailed Pygmy Tyrant and Black-capped Pygmy Tyrant (the first species usually being considered marginally smaller).

The Black-capped Pygmy Tyrant (Myiornis atricapillus) is the smallest passerine bird in its range, though larger than its cousin, the Short-tailed Pygmy Tyrant.

The following species are contained in Myiornis:
