 Many, but by no means all true finches have strong sexual dichromatism, the females typically lacking the bright carotenoid markings of males.The finches have a near-global distribution, being found across the Americas, Eurasia and Africa, as well as some island groups such as the Hawaiian islands.They are absent from Australasia, Antarctica, the Southern Pacific and the islands of the Indian Ocean, although some European species have been widely introduced in Australia and New Zealand.
