Breeding pair is a pair of animals which cooperate to produce offspring. In contrast to any two copulating animals, the term breeding pair indicates some form of a bond between the individuals. For example, many birds mate for a breeding season or sometimes for life. They may share some or all of the tasks involved: building a nest, incubating the eggs and feeding and protecting the young. The term is not generally used when a male has a harem of females, such as with mountain gorillas. “Animalia” redirects here. ...
