The long-tailed parakeet was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in 1780 in his Histoire Naturelle des Oiseaux.

[2] 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.

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

The long-tailed parakeet is able to live in a wide variety of habitats such as in swamp forests, lowland evergreen forest, oil palm plantations, coconut plantations, gardens, public parks, and is a frequent visitor to agricultural areas (especially those who yield tropical fruits and seeds).

[10] This bird species tend to find a breeding area or nest in a high tree trunk almost same behavioral as the Psittacidae family.
