Recent studies have revealed a special survival mechanism for a bird living on the east coast of the US. Now it's called the world's most promiscuous bird. The saltmarsh sparrow, that lives in the marshes of Connecticut, was found to have high levels of multiple mating. The scientists found that 95% of females mated with more than one male during each nesting period. They assume that this unusual behaviour could be a survival mechanism due to coastal flooding. Using DNA analysis and studying the birds mating behaviour in the marsh habitat, the researchers revealed the highly promiscuous activities of the bird. The results were published in the journal The Auk.
