Popis:	We describe the vocalizations of the Christmas Island Warbler Acrocephalus aequinoctialis, endemic to Christmas and Washington Islands, central Pacific Ocean, in the absence of other land birds and natural predators. Its vocal signals are simple when compared to most Acrocephalus. We explain this simplicity as the result of a lack of interspecific interactions, a monogamous life style, large permanent territories, open dry habitat and limited interaction among neighbouring individuals.
