Such animals do not exclusively engage in homosexual behavior. At best, you can claim there are "bisexual animals." However even if there are "bisexual" or even "homosexual" animals, until you can prove that there is an evolutionary advantage to homosexual behavior the only possible reason for any homosexual behavior among animals is a biological glitch since the underlying purpose of sexual behavior is reproduction and reproduction does not result from homosexuality.
