Excessive exploitation of natural resources and devastation of wild nature leads to drastic biodiversity decline. Macaws are endangered by trade for their beautiful colourful feathers, ability to learn to talk and become great companion parrot. Eight of the sixteen species of macaws are classified as vulnerable, endangered or critically endangered and all populations of macaws are decreasing. Species Cyanopsitta spixii is extinct in wild nature. Aims of my thesis are evaluation of world trade with species of Arini tribe, according to the temporal aspect, country of export, country of import and for individual species. In the second part of thesis are complete information about biology and biogeography of macaw species, their occurrence in nature and breading in captivity. The first analysis of trade with macaw's species provides statements about export and import countries, most traded species and commodities, source of the specimens and purpose of the transaction. Results of analysis shows, that in during period 1981 - 2013 was traded with 260 476 specimens. The most traded species were Ara ararauna, Ara chloroptera and Diopsittaca nobilis. Countries with highest export were Guyana, Bolivia and South Africa and country with highest import was The United States of America.
