The tufted coquette (Lophornis ornatus) is a tiny hummingbird that breeds in eastern Venezuela, Trinidad, Guiana, and northern Brazil.

The tufted coquette was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in 1781 in his Histoire Naturelle des Oiseaux.

[3] The bird was also illustrated in a hand-coloured plate engraved by François-Nicolas Martinet in the Planches Enluminées D'Histoire Naturelle which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text.

[4] Neither the plate caption nor Buffon's description included a scientific name but in 1783 the Dutch naturalist Pieter Boddaert coined the binomial name Trochilus ornatus in his catalogue of the Planches Enluminées.

The male has a rufous head crest and a coppery green back with a whitish rump band that is prominent in flight.
