Abstract

Attempts of interbrood food theft (food kleptoparasitism) from chicks of Grey Heron (Ardea cinerea) by foreign nestlings are reported from three heronries situated in northern Poland. Such behavior was observed more often in two of the three sites studied. In one colony, it was recorded occasionally. Possible reasons of intercolonial differentiation in food theft attempts occurrence are discussed.
