Gay rights activists have protested at a north German zoo's
plans to test the sexual orientation of six male penguins which
have displayed homosexual traits.
Bremerhaven's Zoo am Meer said it would introduce four extra
female penguins from Sweden to the group to see if the males
really were gay.
But zoo director Heike Kueck said "gay groups worldwide have
been cursing us since that announcement".
The zoo says it just wants to encourage the rare Humboldt
penguins to breed.
The males have been observed trying to mate with each other and
trying to hatch offspring out of stones.
"We don't know whether the three male pairs are really
homosexual or whether they have just bonded because of a
shortage of females," said Mrs Kueck, quoted by Germany's Der
Spiegel news magazine.
Gay groups insisted that penguins had a right to form couples
without human interference, she said.
"Nobody here wants to forcibly separate homosexual couples," she
said.
Only one baby Humboldt penguin has been born at the zoo, which
has six males and four females, Der Spiegel reports.
