Breeding
· In Marmosets,only the dominant female breeds.The other females are prevented from coming into heat by the dominant's aggressive behaviour--staring,poking and general intimidation,and in some,by her pheromones as well.The breeding female may change with a new breeding season
· Marmosets live in pairs or family groups in which only the dominant pair breeds.
· In the Callitrichids family there is very rarely inbreeding,families can sometimes grow to ten or more animals.
· They are highly social and have a dominance hierarchy.Only the dominant female gives birth,and everyone in the family,including the dominant male,helps carry the infants.
· The Best Father Award may go to Marmosets.These fathers are highly devoted to their babies.The father helps the mother deliver the babies:biting off the umbilical cord,cleaning up the afterbirth,receiving and washing the babies.The mother looks after them during the first few weeks,but later the father (or if there are two males,the fathers) take over,carrying the babies on their backs and returning them to the mother every 2-3 hours for breast feeding.Although juveniles and non-breeding females may also help out,the fathers do most of the work.Some have pointed out that this behaviour is more similar to some birds than to other primates!This behaviour probably helps improve the survival of the babies and the group for various reasons:
· To share the physical burden of the babies,which can be very large in size relative to the adults.
· To share the tasks of looking out for predators,looking after infants and foraging.Adults often share food with babies,juveniles and sometimes even adult children.
· The experience also gives juveniles good practice to become better parents when they grow up.Juveniles removed too early from their social group later make poor parents.
