In many cities in Western Europe it recorded a drastic decline, mainly pointing to the modernization construction, but also a worsening food conditions nestling because of the abundance deficient feeding grounds (Luniak 2005). no certainty that the nests were robbed in 2013 as in 2015.},
 abstract={It is currently difficult to clearly identify how changes in the waste collection sys?tem will affect the condition of the national population of Jackdaws and the species inhabiting urban areas. The observations in Mogielnica indicate that the searching of buildings with nests by Jackdaws will probably increase. A similar phenomenon wherby Kestrels "Falco tinnunculus" hunt prey in buildings (Swift, Bats "Chiroptera") has been described (Mikula et al.2013).},
