From the
BBC:
Same-sex pairs of monogamous birds are just as attached and faithful to each other as those paired with a member of the opposite sex.
The insight comes from a study of zebra finches - highly vocal, colourful birds that sing to their mates, a performance thought to strengthen the pair's bond.....
The findings indicate that, even in birds, the drive to find a mate is far more complicated than simply the need to reproduce.
"A pair-bond in socially monogamous species represents a cooperative partnership that may give advantages for survival," said Dr Elie. "Finding a social partner, whatever its sex, could be a priority."
There are many other examples of same-sex pairing in the avian world.
In monogamous gulls and albatrosses, it gives females the chance to breed without a male partner.
"Female partners copulate with a paired male then rear the young together," Dr Elie explained.
Homosexual behavior in animals is well documented in multiple species, not just birds. (More on the
