Provide artificial nesting sites for ground and tree-nesting seabirds Bird Conservation

A replicated study in 1987-1990 of a managed wetland in Macedonia, Greece (Pyrovetsi 1997) found that the target species, Dalmation pelicans Pelecanus crispus, did not benefit consistently from artificial habitats although other waterbirds did. Two constructed rafts and one artificial island were used extensively by a variety of waterbirds as resting and foraging sites. Common terns Sterna hirundo colonised the rafts in both years (average 12 nests and 14 fledglings / raft). Dalmatian pelicans did not colonise the rafts. Many waterbirds, including pelicans, were observed roosting on the island but no successful breeding took place in 1988-1989. In April 1990, 26 pelicans colonised the islands. Thirteen nests contained 1-2 eggs each. By June, however, the pelicans had deserted the island, no eggs remained and some nests had been destroyed. The authors speculate that fisherman landed on the island and removed the eggs. Pelicans did not return to the island.
