Gniazdowanie gawrona Corvus frugilegus w Warszawie w latach 2013-2014
Journal Title: KULON - Year 2014, Vol 19, Issue
Abstract
In 2013-2014, breeding colonies of the Rook Corvus frugilegus were monitored in the area of the whole Warsaw within the administrative boundaries from the 1980s. In 2013, 24 breeding sites were recorded, and only 13 in 2014. The total number of nests was 511 and 301, respectively. The described number of rooks at the scale of the whole Warsaw was similar to that known from the literature data in the 1980s. However, the proportion of birds nesting in the central part of Warsaw significantly increased.
