The article describes the co-operative breeding behavior of the Rufous-fronted Thornbird Phacellodomus rufifrons, a Neotropical endemic Suboscine passerine in the family Furnariidae. Co-operative breeding is a social system in which more than a pair of individuals help with a breeding attempt at a single nest or brood. Assistance consists of territory defence, egg incubation and nestling feeding. This social system has been reported for 308 bird species across 27 families, accounting for 3.2 percent of all 9672 described species. Usually, the aid-givers are mature offspring with some relationship to the breeders. |
