The displacement of the traditional culture of Nauru by contemporary western influences is evident on the island. Little remains from the old customs. The traditions of arts and crafts are nearly lost. Arts and crafts The inhabitants of Nauru wear the usual tropical clothes: short trousers and light shirts. Fishing still follows a traditional method: the island anglers wait in small light boats for fish to arrive. The custom of fishing by trained frigatebirds has been preserved.
