Možnosti řešení problému populací holubů v českých městech / Possible ways to deal with pigeon population problem in Czech townsTrnková, Karla January 2016 (has links)
The thesis addresses issues related to the overbred population of feral pigeons (Columbia livia forma Domestica) in Czech towns. It approaches the subject from procedural, bureaucratic perspective. Specifically, the thesis examines the factors which affect the selection of methods of the feral pigeons' population regulation in four Czech towns: Special attention is devoted to the question whether the method of controlled city dovecotes, used to regulate pigeon populations, could come in useful in the Czech context. Research carried out for the thesis is qualitative; the data comes from semi-structured interviews with experts. Analysis of the collected data focuses on verification of authenticity of the provided information. Subsequently, effectiveness of cage entrapment, which considerably prevails over the other methods used, is considered in ethical, ecological, and economic respect. The thesis also surveys the health risk posed by the feral pigeon population to public and how views of the public concerning the issue affect the regulation process. The overall aim is to highlight the drawbacks of the decision making process, offer possible alternatives, and prompt more research.
