More and more species have been documented to display homosexual behavior. Here's a report from Telegraph.co.uk
Homosexual Behaviour Widespread in Animals According to New Study
From Louise Gray
Homosexual behaviour is a nearly universal phenomenon in the animal kingdom, according to a new study.
The pairing of same sex couples had previously been observed in more than 1,000 species including penguins, dolphins and primates.
However, in the latest study the authors claim the phenomenon is not only widespread but part of a necessary biological adaptation for the survival of the species.
They found that on the Hawaiian island of Oahu, almost a third of the Laysan albatross population is raised by pairs of two females because of the shortage of males. Through these 'lesbian' unions, Laysan albatross are flourishing. Their existence had been dwindling before the adaptation was noticed.
Other species form same-sex bonds for other reasons, they found. Dolphins have been known engage in same-sex interactions to facilitate group bonding while male-male pairings in locusts killed off the weaker males.
A pair of "gay" penguins recently hatched an egg at a German zoo after being given the egg that had been rejected by its biological parents by keepers.
Writing in Trends in Ecology & Evolution, Dr Nathan Bailey, an evolutionary biologist at California University, said previous studies have failed to consider the evolutionary consequences of homosexuality.
He said same homosexual behaviour was often a product of natural selection to further the survival of the species.
Dr Bailey said: "It's clear same-sex sexual behaviour extends far beyond the well-known examples that dominate both the scientific and popular literature – for example, bonobos, dolphins, penguins and fruit flies.
"Same-sex behaviours – courtship, mounting or parenting – are traits that may have been shaped by natural selection, a basic mechanism of evolution that occurs over successive generations," he said.
"But our review of studies also suggests that these same-sex behaviours might act as selective forces in and of themselves."

and this whole time I thought Maui was lesbian central!
an interesting tid-bit from the news-of-the-world appeared in one of the local gay rags :
POLAND
Gay elephant riles politician
a politician is angry that the city zoo bought an elephant that prefers the company of other males.
"we didn't pay 37 million zlotys for the largest elephant house in Europe to have a gay elephant live here," said Michal Grzes, a conservative council-member in the city of Poznan.
the 10-year old elephant, named Nino, has displayed aggressive behavior toward females, including pushing them into the pool. however his attitude to males has been called "affectionate."
is Nino gay? zookeepers say it's impossible to tell, as elephants don't reach adolescence until about 14.
