Breeding pair is a pair of animals which cooperate over time to produce offspring with 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 (zoology) of females, such as with mountain gorillas.
True breeding pairs are usually found only in vertebrates, but there are notable exceptions, such as the Lord Howe Island stick insect. True breeding pairs are rare in amphibians or reptiles, but fairly common with fish (e.g. discus) and especially birds. Breeding pair arrangements are rare in mammals, where the prevailing patterns are either that the male and female only meet for copulation (e.g. brown bear) or that dominant males have a harem (zoology) of females (e.g. walrus).
Famous quotes containing the words breeding and/or pair:
“The test of a man’s or woman’s breeding is how they behave in a quarrel. Anybody can behave well when things are going smoothly.”
—George Bernard Shaw (1856–1950)
“You are always looking for already-felt emotions, just as you like to get an old pair of trousers back from the cleaners, which seem new when you don’t look too closely. Artists are cleaners, don’t let yourself be taken in by them. True modern works of art are made not by artists but quite simply by men.”
—Francis Picabia (1878–1953)
