Cooperative breeding is a social system in which individuals contribute care to offspring that are not their own at the expense of their own reproduction. When reproduction is monopolized by one or few of the adult group members and most adults do not reproduce, but help rear the breeder’s offspring, the majority of these cooperative breeding species exhibit high reproductive skew. However, there are plural breeding species with low reproductive skew, in which the subordinates commonly breed. This kind of cooperative breeding systems is particularly rare and includes communal breeding, in which more than one female lays eggs or gives birth to young. Cooperative breeding is different from alloparenting, which is simply the act of caring completely for another conspecific's offspring but not at their own expense.

Famous quotes containing the words cooperative and/or breeding:
“Then we grow up to be Daddy. Domesticated men with undomesticated, frontier dreams. Suddenly life—or is it the children?—is not as cooperative as it ought to be. It’s tough to be in command of anything when a baby is crying or a ten-year-old is in despair. It’s tough to feel a sense of control when you’ve got to stop six times during the half-hour ride to Grandma’s.”
—Hugh O’Neill (20th century)
“Good breeding and good nature do incline us rather to help and raise people up to ourselves, than to mortify and depress them, and, in truth, our own private interest concurs in it, as it is making ourselves so many friends, instead of so many enemies.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
