Synanthropic Species - Birds in Poland

The coming century is featured by the ongoing urbanisation of the environment. All large spaces are rejected from the natural landscape and taken by mega-cities, uniting in an urban agglomeration with a population of tens of millions people. Urbanisation as a process of expansion of the residential landscape is held in the format of the global transformation of the environment, which creates new large-scale landforms on the earth's surface.

The process of urbanisation has a direct impact on birds via changes in global ecosystem processes and the transformation of natural habitats into the residential and industrial landscape. Indirectly the birds are influenced by changes in predation, competition, disease, etc.

In European countries, the problem of studying of the synanthropic species and their behaviour is the subject of many scientific works. Ornithologists and environmentalists are concerned about the conservation of bird habitat in the urbanising cities in Europe. For example, much attention has been paid to the study of ravens on the territory of Poland.

For the first time ravens massively settled in Warsaw and Krakow in the 1950s. In the decades that followed, they chose to breed in large forests, which are located in the suburban areas of the cities. The fact is that at present days nesting birds also prefer suburban areas. According to scientists, the largest number of breeding birds that lived in the cities did not exceed 20 pairs. In the second half of the 20th century the ravens started to nest and live in urban parks of Polish cities. In the 1980's when the population of Poland grew significantly, there had also been an increase in the number of birds in almost all Polish cities. In the period from the 1990s to the present days the population of ravens in Poland is rising slightly, however, it is not reduced. Now the ravens are already nesting on the transmission line poles, on farms, in garbage dumps and slaughterhouses. Thus, we can conclude that the birds still breed more actively on the peripheral territories.

It is obvious that the process of urbanisation will accelerate and continue to grow to cover more and more of the world space that will lead to significant ecosystem change. For this reason, for those who are concerned about the preservation of fauna and flora the study of the of animal synantropization processes is a priority.

The coming century is featured by the ongoing urbanisation of the environment. All large spaces are rejected from the natural landscape and taken by mega-cities, uniting in an urban agglomeration with a population of tens of millions people.
