Sexy sparrow exposed as world's most promiscuous bird

A bird living on the coast of the US is the world's most promiscuous bird, say scientists.

The saltmarsh sparrow, a bird that lives in the marshes of Connecticut, was found to have extreme levels of multiple mating.



The researchers found that 95% of females mated with more than one male during each nesting period.

This unusual behaviour could be a survival mechanism due to coastal flooding, researchers say.
