- Jean Baptiste Leschenault de la Tour sailed from France as a naturalist on Nicolas Baudin's expedition to Australia. In April 1803 he fell ill and had to be put ashore at Timor. He spent the next three years on Java returning to France in July 1807 with a large collection of plants and birds. Many of the new bird species found on the Baudin Expedition were described by Louis Pierre Vieillot in Nouveau dictionnaire d'histoire naturelle (1816–1819).The specimens are in Muséum national d'histoire naturelle in Paris.
