Szukana fraza: [Abstract = "From 2004 to 2012, the number of Jackdaws declined on the plots Słoneczne and Old Town. On the plot Winnica the number of breeding pairs remained the same. In Park Tysiąclecia Jackdaws increased from two pairs in 2004 to six pairs in 2012. This increase may have been caused by the settlement of birds formerly breeding in the Old Town where numbers were declining, probably due to the loss of suitable nest sites."]
