Abstract

An ornithological study was carried out on the lagoon of Calich. A census was made on 100 species of birds of which 66 «Non Passeriformes» and 34 «Passeriformes». 65 species are or have been migrators. 14 species are or have been nesting annually, 6 are nesting but not wintering, 15 are probably nesting. The category with the largest number of species proved to be the CHARADRUFORMES with 25 species. The most numerous species inAnas querquedula. 6 species (Podiceps ruficollis, Ardea purpurea, Ixobrychus minutus, Circus aeruginosus, Porphyrio porphyrio, Fulica atra) are extinct owing to the resu1ts of land rec1amation in 1938-40. As a second land rec1amation is in progress, some proposals are made for the ornithologycal protection and the conservation of the ecological system of Calich.
