Contains analysis of 648 droppings of this species on 10 ha area of Algiers costal shows that it is getting a high and easy adaptability on the trophic plan. It is fed there, especially of Tapinoma Niggerimum (50%), of Pheidole, pallidula (25.8%), of Tetramorium biskrensis (14.5%) in 1994. Ant Plagiolepis barbara which reached a value of 33.2% in 1998. In 1994 among ingested Formicidae M. Barbara, A.Testaceo pilosa and Crematogaster scutellaris are weakly sampled and characterized by negative values of Ivlev's selection index while in 1998, this index showed values of +99 for ants the most selected such as T.biscrensis, P.barbara T. Nigerrimum and P. Pallidula. Others ant's species are not so much looked for. Compared to all ants consumed within the three years of study, most abundant specie is T. nigerrimum. Myrmecophage diet of Wryneck in suburban area of Algiers is of opportunist type showing large trophic adapt...
