Abstract

Feeding data of Herons frorn the Ebro Delta
Stomach contents of nine adult Herons coming from the Ebro Delta have been analyzed: four of Little Egret (Egretta garzetta), four of Grey Heron (Ardea cinerea) and one of Night Heron (Nycticorax nyclicorax). Results show that, these Little Egrets fed mainly in brackish waters, whereas Grey Herons and Night Herons caught preys in freshwater masses.
