Several breeding parameters of the great cormorant (Phalacrocorax carbo sinensis) were studied in Greece in 2001 and 2002 and were found to be generally higher at Lake Kerkini than in the other colonies. Fledging success (proportion of hatched eggs that led to fledged nestlings) was significantly higher at Lake Kerkini and in the Axios Delta in both ...

Animal Behaviour, 1999
In many species of colonial seabirds, young birds visit colonies in the years before they start breeding. This prospecting behaviour may allow them to obtain information that could enhance their future breeding success. We examined the reproductive consequences of prospecting behaviour in the colonial great cormorant, and found support for this idea ...

Sexual differences in the diet of great cormorants Phalacrocorax carbo sinensis wintering in Greece
European Journal of Wildlife Research, 2009Sexual differences in the diet of the great cormorant, Phalacrocorax carbo sinensis, were studied in four Greek wintering areas, the Amvrakikos Gulf, the Axios and Evros Deltas and the Messolonghi Lagoon, through the analysis of stomach contents. Great cormorants are birds sexually dimorphic in size, with males being generally larger than females ...
