Effect of species composition on the sociality of macaw species in mixed aviaries
DUŠKOVÁ, Eliška
The main aim of this work was to find out and write down information about parrots and the genus Macaw itself. Then, using the information found, to say which species could work well together in a mixed aviary. In this work, the reader can read not only about the habitat of macaws, but also about the nesting habits, or get a glimpse into the social structure of the life of these colourful birds. The work focuses specifically on four selected species. The work focuses speci-fically on four selected species. These are the Macaws, Blue ? and ? Yellow macaws, Scarlet Macaws, Red ? and ? Green macaws, The Chestnut ? fronted macaws. For zoo visitors, mixed aviaries are very attractive as there is always something going on. One of the chapters is therefore dedicated to selected mixed aviaries in Czech and international zoos. Thanks to the obtained information about macaws, I have written in this thesis the factors influencing the assembly of a mixed macaw aviary, what to avoid when com-bining macaws and last but not least, suggestions for measures aimed at the successful assembly of mixed flocks of macaws.

Arini - trade, captive breeding, distribution pattern
KAMENICKÁ, Karolína
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.
