THE DAILY TELEGRAPH: Birds are being turned gay because there is too much mercury in their diet, scientists have revealed.
Researchers in Florida and Sri Lanka studied the effect of the metal in white ibises' diets to find out why breeding was down.
They found the higher the dose of mercury in the wading birds' food pellets, the more likely a male bird was to pair with another male.
Dr Peter Frederick from the University of Florida, who led the study, said: "We knew mercury could depress their testosterone levels but we didn't expect this.
"We're seeing very large reproductive effects at very low concentrations of mercury so we really need to be paying more attention to this." >>> | Thursday, December 01, 2010
