Male and Female Animals Together (not humans)

Brief

I am looking for your photos showing at least one male and at least one female of the same animal species photographed together. It can be anything from a pair of majestic lions to graceful birds, displaying intricate courtship rituals or tender moments of companionship etc., portraying the beautiful partnership between the male and female animals. It can be any animal species, but not humans. Photos can be either in colour or black and white.
