Mercury ‘turns birds gay’

December 1, 2010

Consuming high doses of the chemical mercury makes some birds appear to turn gay, scientists say.

It is known that mercury reduces breeding rates in white ibises but scientists in Florida and Sri Lanka were surprised to discover that the higher the dose given to male birds, the more likely they were to try to mate with another male.

Researchers gave birds food pellets containing mercury and found that males which received higher doses were more likely to find male partners and shun mating displays to attract females
