Do gay swans mate
Mute swans, for instance, form bonds that remain for life in about 97% of pairs. Trumpeter swans also mate for life, forming bonds between five and seven years of age. This strong, long-term pair-bond is the general rule for many swan species. While socially monogamous, swans may not always be genetically monogamous.

Both male and female swans have been observed forming same-sex pairs in which they will court, nest, and rear eggs. Studies have found that this behaviour is more persistent in male swans than in females and particularly Australian male black swans , who form stable, long-lasting same-sex relationships with each other.

The black swan, Cygnus atratus is a large waterbird which breeds mainly in the southeast and southwest regions of Australia. An estimated one-quarter of all black swans pairings are homosexual and they steal nests, or form temporary threesomes with females to obtain eggs, driving away the female after she lays the eggs. [13][14].

Over 1, animal species engage in same-sex coupling and parenting. Even more regularly engage in homosexual or bisexual relationship.

Australian black swans are classed also as monogamous birds, and as is the case with other swan species, the general consensus is that they, too mate for life. Surprisingly, observations show that up to 38 percent of cygnets are born from copulation with a different mate.

Swans do indeed form long-term bonds and generally mate for life. Swan pairs can “divorce,” but that’s pretty uncommon. According to the National Audubon Society, Mute Swans that successfully raise broods “divorce” 3% of the time. If they don’t raise young, 9% of swan pairs divorce each other.

Each spring when they return to the Public Garden the Mayor leads a grand parade and hundreds of kids arrive dressed as swans and ducks. They even nicknamed one swan duo that never leaves each other's side "Romeo and Juliet.

In most cases, females are younger than males when the pair bond is formed. Juvenile swans live in flocks until they reach sexual maturity and usually find their mate within the flock. Non-breeding pairs often mimic the behaviour of breeding pairs, displaying to each other, defending a defined territory, and even building partial nests.

Among giraffes, there's more same-sex than opposite-sex activity. In fact, studies say gay sex accounts for more than 90 percent of all observed sexual activity in giraffes.
