Wetmore Order
A sequence for listing bird species devised by American ornithologist Alexander Wetmore round about 1930. It places related groups close to each other, starting with the most primitive and ending with the most advanced. The Wetmore Order is still the generally accepted sequence, although subsequent research in taxonomy has increased knowledge of the relationships between birds and therefore many modifications have been necessary. The most recent revised version is the Voous order.From Peter Weaver's Birdwatcher's Dictionary
