Přehled základních aspektů hnízdní biologie ptáků rodu Merops ve vztahu k jejich chovu. / Overview of the basic aspects of the nesting biology of birds of the genus Merops in relation to their breeding.

ZEMANOVÁ, Jitka January 2014 (has links)
The European Bee-eater (Merops apiaster) is species of open landscapes with solitary trees with expressive and unmistakable colour. The origin is in North Africa and southern Europe, in the Czech republic is found in southern Moravia. The expansion of this kind is shifting to the north due to changes in landscape. For European bee-eater is typical of nesting burrows in the sand wall. The aim of this thesis was to describe the biology of African species of the genus Merops, to assess the situation of nature conditions for the kind of Merops apiaster, to describe the breeding of this species in captivity and to evaluate the success existing rearings in selected breeding institutions. In this thesis was described the breeding of European Bee-eater in Vienna Zoo, Dresden Zoo and Frankfurt Zoo, the breeding of Northern Carmine Bee-eater (Merops nubicus) in Zoo in Plzeň and the breeding of White-fronted Bee-eater (Merops bullocoides) in Vienna Zoo. Farther was described the breeding of all three species in private breeding of Mr. Drozdek in the Český Rudolec.
