Echo parakeet [SEP] Taxonomy
Green parakeets were mentioned in the accounts of early travelers to the Mascarene Islands of Réunion and Mauritius. They were first recorded on Réunion in 1674 by the French traveler Sieur Dubois, and on Mauritius in 1732 by French engineer Jean-François Charpentier de Cossigny. The green parakeets of Réunion were referred to as "perruche à double collier" ("double-collared parakeet") by the French naturalists Mathurin Jacques Brisson, in 1760, Comte de Buffon, in 1770–1783, and François Levaillant, in 1801–1805, who described them from specimens that reached France. In 1783, the Dutch naturalist Pieter Boddaert coined the scientific name "Psittacus eques", based on a plate by the French artist François-Nicolas Martinet, which accompanied Buffon's account of the Réunion bird in his work "Histoire Naturelle".
