The study describes the development of the population of Magpies "Pica pica" in the city of Zielona Gora, western Poland, based on earlier reports and a recent count in 2016. In the first half of the 20th century, there were only 5-7 pairs, corresponding to a density of 1.4 pairs/km2. At that time 2-3 pairs nested in the city center. ; In 2006 and 2007 a further study revealed very high values of 26.9 and 27.6 pairs/km2, respectively, followed by a subsequent decrease to 6.6 pairs per km2 in 2012. However, the population seems to have stabilized at that level, as shown by the results of the most recent count in 2016 (6.4 pair/km2).
