We had a chance to observe grey partridge (Perdix perdix) directly from an office located in industrial zone Cernovicka terasa in Brno city. There were many factories built on former meadows and fields during last few years, therefore the grey patridges lost their natural refuge. It is an interesting finding, how grey patridges reacted to such significant change of the landscape. They almost fully lost their natural fear of a man. Formerly numerous grey patridge is now endangered species in the Czech Republic.
