Practical importance and protection of synanthropic birds

Abstract

A natural food chain and food web optimizes the number ratio of individual biological species. However, in anthropogenic ecosystems, not natural laws, but human economic activity plays an important role. Therefore, mass reproduction of harmful insects and weeds is always expected in anthropogenic ecosystems. In this regard, synanthropic birds draw attention. Their activity has a positive effect on stability in anthropogenic ecosystems.

Most of the 177 bird species in different stages of the synanthropization process in our research areas (Absheron Peninsula) have economic losses that unexceed their benefits,

only two ravens (Corvus ruficollis, C. splandens) and house sparrows (Passer domesticus) need to be considered. The remaining species benefit the economy by eating pests and other invertebrates or seeds of weeds. Noted that when we consider the examined birds, we don’t take into account their medical and veterinary importance.

Information on the spread of external and internal parasitism by synanthropic birds increases every year.
