About the Spectacled Tyrant

The spectacled tyrant (Hymenops perspicillatus) is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is found in Argentina, Bolivia, Brazil, Chile, Paraguay, Uruguay, and as a vagrant to Peru. The spectacled tyrant was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the wagtails in the genus Motacilla and coined the binomial name Motacilla perspicillata. Gmelin based his description on "Le clignot ou traquet à lunette" that had been described in 1778 by the French polymath the Comte de Buffon in his Histoire Naturelle des Oiseaux. The spectacled tyrant is now the only species in genus Hymenops that was introduced in 1828 by the French naturalist René Lesson. The genus name is from Ancient Greek humēn meaning "skin" or "membrane" and ōps meaning "eye". The specific epithet perspicillatus is Modern Latin meaning "spectacled". Within the family Tyrannidae the spectacled tyrant is sister to the genus Knipolegus containing the black tyrants.

The spectacled tyrant has two subspecies, the nominate H. p. perspicillatus (Gmelin... Wikipedia →
