For these animals, there is documented evidence of homosexual behavior of one or more of the following kinds: sex , courtship , affection , pair bonding , or parenting , as noted in researcher and author Bruce Bagemihl 's book Biological Exuberance: Animal Homosexuality and Natural Diversity. Bagemihl writes that the presence of same-sex sexual behavior was not "officially" observed on a large scale until the s due to observer bias caused by social attitudes towards nonheterosexual people, making the homosexual theme taboo. They must realize that animals can have sex with who they will, when they will and without consideration to a researcher's ethical principles. Sexual behavior takes many different forms, even within the same species and the motivations for and implications of their behaviors have yet to be fully understood. Bagemihl's research shows that homosexual behavior, not necessarily sex , has been documented in about five hundred species as of , ranging from primates to gut worms.

A male is born with a predisposition to mate with a female, since the aim is the reproduction of the species. This is something determined by nature.

In , a team of scientists set off on the Terra Nova Expedition to explore Antarctica. He chronicled the animals' daily activities in great detail. In his notebooks, he described their sexual behaviour , including sex between male birds. However, none of these notes would appear in Levick's published papers.
