| Summary: | The first aim of this study was to determine the scale of population change of common swift colonizing residential blocks made in the concrete panels technology in Poznan. The second aim was to quantify ecosystem services provided by birds which exist nowadays and potentially if their habitats would still exist. Regulating services provided by birds in Polish cities were studied by Kamiński, Luniak, Zimny but mainly as part of urban ecology or zoology studies. Abroad researches include also studies in small cities and agricultural areas. None of these studies were dedicated to common swift. Additionally many researchers on ecosystem services provided by birds use only descriptive methods. As Wenny et al. states there is the need to quantify ecosystem services provided by birds, and this research is part of this trend. There is also a wide range of international literature about behavioural studies of common swift, including amount of consumed insects. But none of studies mentioned above were quantitative research on regulating services provided by common swift population in a given area like presented in this paper. Celem badań było określenie skali zmian populacji jerzyka zwyczajnego (Apus Apus) zasiedlającej bloki mieszkaniowe w Poznaniu oraz ustalenie zmian w zakresie świadczonych przez nie usług ekosystemów. W artykule wskazano, że termodernizacja budynków często prowadzi do likwidacji siedlisk, a tym samym do zmniejszenia populacji ptaków je zamieszkujących. Wykazano, że w Poznaniu pozostało tylko 15% bloków mieszkalnych nie poddanych termomodernizacji. Tylko 4% z budynków po renowacji posiada zainstalowane skrzynki lęgowe dla ptaków. Szacuje się, że utracono ok. 86% populacji jerzyka na Osiedlu Mlodych – największej spółdzielni mieszkaniowej w Poznaniu. Utracono również usługi ekosystemów w postaci zjadania przez ptaki blisko 2,5 tony lub 25 tys. latających insektów na sezon z obszaru Poznania i okolic. |
