Evolution and Taxonomy of White-cheeked Geese
Dr. Anderson's volume is an extension of Hanson's work (White-Cheeked Geese) in four ways.
(1) A detailed statistical analysis of Hanson's taxonomy highlighted by a search for intergrades.
(2) A revision of Hanson's taxonomy based on the re-analysis.
(3) An evolutionary scenario accounting for the taxa.
(4) A color plate section illustrating various plumage characters for about 80 taxa.
