Risks of Mass Concentrations of Birds

Abstract

© 2019 Published under licence by IOP Publishing Ltd. The basis of an urban ornitotsenoz is formed by several synanthropic mass bird species whose numbers are hundreds of times larger than the small and rare species. The vital activity of mass species leads to undesirable consequences for humans, reduces the biological diversity of ornithocene. Populations of synanthropic birds are reservoir and source of pathogens of dangerous zoonoses and zooantroponoses. The contact between the bird and the man takes place in the places of their accumulation: at transport stops, in parks and feeding places. To identify the percentage of patients with chlamydia rock pigeons in the city of Kazan were investigated in the serum and the pathological material of pigeons that live in different parts of the city. By managing the factors influencing on magnitude of population it is necessary to increase stability of a city ornitotsenoz. The stability of the urban ornithocenosis is a necessary condition for a healthy environment.
