'Gay penguins' rear adopted chick
Two "gay" male penguins have hatched a chick and are now
rearing it as its adoptive parents, says a German zoo.
The zoo, in Bremerhaven, northern Germany, says the adult males - Z
and Vielpunkt - were given an egg which was rejected by its biological
It says the couple are now happily rearing the chick, said to have
reached four weeks old.
The zoo made headlines in 2005 over plans to "test" the
sexual orientation of penguins with homosexual traits.
Three pairs of male penguins had been seen attempting to mate
with each other and trying to hatch offspring from stones.
The zoo flew in four females in a bid to get the endangered birds to
reproduce - but quickly abandoned the scheme after causing outrage
among gay rights activists, who accused it of interfering in the

and got straight down to raising it," said a zoo statement.
"Since the chick arrived, they have been behaving just as you
would expect a heterosexual couple to do. The two happy fathers spend
their days attentively protecting, caring for and feeding their

'Drive to mate'
There have been previous reports of exclusive male-to-male pairings
among penguins, some of which have also included the rearing of
Homosexual behaviour is well documented in many different animals, but
it is not understood in detail, says Professor Stuart West, an
evolutionary biologist at the University of Oxford.
Professor West says it has been suggested that homosexual activity
could serve various purposes - for instance, it may relate to social
bonding and establishment of dominance among bonobo chimps, while in
some bird species, females may come together to rear young.
Other animals may simply exhibit a "drive to mate", while
others may, like humans, enjoy non-procreative sexual activity.
"Homosexuality is nothing unusual among animals,"
Bremerhaven zoo said on Wednesday.
"Sex and coupling up in our world do not necessarily have
anything to do with reproduction."
