The White Stork (Ciconia ciconia) bred in the former district of Kutno in 1985 at
a density of 5.33 pairs/100 km 2. The mean number of nestlings per nest occupied by
a pair was 2.24 and the mean number of nestlings per nest with nestlings was 2.73. 93%
of the nests were situated on trees (mainly poplar trees) and 92% were up to 100 m from
buildings. Storks nesting in the eastern part of the former Kutno district show a regular
distribution of nests, while those from the western part a contagious one. The mean
number of nestlings was statistically significantly higher in the eastern part, which can
be explained by better foraging conditions there due to many river valleys.Zadanie pt. „Digitalizacja i udostępnienie w Cyfrowym Repozytorium Uniwersytetu Łódzkiego kolekcji czasopism naukowych wydawanych przez Uniwersytet Łódzki” nr 885/P-DUN/2014 dofinansowane zostało ze środków MNiSW w ramach działalności upowszechniającej naukę
