Abstract:

The breeding Ardeidae species of Tunisia.

Nine Ardeidae species breed in Tunisia. About 2,500-3,000 breeding pairs breed each year and more than 12,000 individuals winter. The breeding population includes 8 regular species: Grey Heron Ardea cinerea, Purple Heron Ardea purpurea, Black-crowned Night Heron Nycticorax nycticorax, Cattle Egret Bubulcus ibis, Squacco Heron Ardeola ralloides, Little Egret Egretta garzetta, Little Bittern Ixobrychus minutus and Eurasian Bittern Botaurus stellaris (for the latter species, breeding is certain but no nest has been found). The Western Reef Egret Egretta gularis is a casual breeder. The Great Egret Casmerodius albus is present all the year round but no nesting has been found.
