About Book
This volume is a complete review of the parrots of South America by a noted authority.
America has a greater number of parrot species (using Peters’ classification, 144, as opposed to 189 for the rest of the world) than any other continent, although the birds do not show such a diversity of form as do those from Australia, for example. The majority are found in the northern part of South America but they actually range from south-eastern Arizona in the USA, where the Thick-billed Parrot occasionally appears in the pine forests, to Tierra Fuego, in the southernmost part of South America, where the Magellan Conure is found
