Albrechtová, Šárka ; Zita, Lukáš (advisor) ; Ledvinka, Zdeněk (referee)
This Thesis is a summary of available sources on the topic of the pet breeding of Forpus parrots and their vocalization. Since the parrotlets became best known in Czech republic as pets 35 years ago, they are not that common as other small species. However it was their vibrant colouring, pleasant vocalization and low breeding demands that enchanted the breeders. In the first part of the Thesis, there is introduction on the taxonomy of the species with emphasis on its history and still changing presence. Also there is general description of the biology of each of the species and subspecies in the nature with their localization. The second part consists of information on the topic of hobby breeding. It summarizes current findings in the form of breeder's advice including information about successful breeding and also emphasises the epizootiology. The last part is dedicated to the topic of vocalization because parrotlets are one of a few species that are capable of referential vocalization. So there is a brief anatomy of syrinx, types of calls and details about referential vocalization. Also, findings from the last 30 years of research are mentioned.
