This Daily Mail story actually predates by almost 2 weeks the AP story I posted March 10 on sex hormones infiltrating the water supply with dastardly consequences. But I just discovered it. Obviously, the 2 are related:

… Scientists at Cardiff University have discovered that the brains of male starlings foraging for worms at a sewage treatment works in South-West England have been subtly changed by being contaminated by oestrogen from the contraceptive pill and hormone replacement therapy (HRT).

The female hormones – present in women’s urine, and passing through the sewage treatment unaffected – caused the part of the brain that controls their song to grow much bigger, causing them to sing at greater length and with even more virtuosity than usual.
The study confirms similar, if slightly differing, research on other birds, which scientists say is adding up to some of the first concrete proof of the effects of gender benders on the natural world….

Researchers at the University of California have found that feeding female finches with a hormone used in HRT has caused them to sing, something hitherto done only by their males….
Yet there have been strange warning signs for decades. Way back in the early 1970s, researchers found that female gulls had taken to nesting together all over the U.S., the males having apparently lost interest.
When the bashful males were caught and examined, they were found to have developed female egg-laying canals.
In the 1980s, researchers in Florida found that alligators were failing to reproduce because their males had mysteriously tiny penises; further investigations revealed that they had developed female hormone patterns – and that turtles in the same waters had developed into hermaphrodites.
Most alarming of all, repeated studies by Britain’s own Environment Agency have shown that about a third of the male roach in rivers and streams right across the country have begun producing eggs, after developing female sex organs.
Again, the problem was traced to oestrogen passing through sewage works – in some areas, near particularly heavy inflows of treated water, all the males were found to be between sexes….

Studies in more than 20 countries have shown that average amounts have fallen by well over half in the past 50 years, from an average of more than 150 million per millilitre to 66 million.
The result is that men are now less than half as fertile as hamsters.
The counts are continuing to plunge by 2% a year, and no end to the decline is in sight. At this rate, the average man will be unable to father children within decades.
Increasingly the sperm crisis is being blamed on a whole host of chemicals, not just synthetic oestrogen, but a wide variety of substances that have become ubiquitous in daily life….
Scientists at Rotterdam’s Erasmus University have found that boys born to mothers exposed to PCBs grew up wanting to play with dolls and tea-sets.
And research at the University of Rochester in New York State has shown that the male children of women exposed to phthalates have smaller penises and other signs of feminisation of their genitals.
Communities exposed to high levels of these and other gender-bender chemicals, from the Great Lakes of North America to the Russian Arctic, have been found to give birth to twice as many girls as boys.
This may offer a clue to the cause of a mysterious shift in the sex of babies worldwide.
Normally 106 boys are born for every 100 girls, in what is thought to be nature’s way of compensating for the fact that males were more likely to be killed hunting or in conflict.
But increasingly this ratio is slipping – it is calculated that 250,000 babies who would have been boys have been born girls in the U.S. and Japan alone….
