Parentage in the cooperative breeding system of long-tailed tits, Aegithalos caudatus
In cooperatively breeding birds multiple maternity and paternity of broods is not uncommon, reproduction often being shared among group members as well as with extragroup members. We investigated the extent of extrapair paternity and intraspecific brood parasitism in a population of cooperatively breeding long-tailed tits. Our aim was to determine the frequency and cause of mixed parentage and ...
متن کاملThe Evolution and Ecology of Cooperative Breeding in Vertebrates
Cooperative breeding – in which some adults forgo independent breeding and remain as subordinates within a group helping to raise the offspring of others – occurs in between 3% and 10%of vertebrates. The structure of such systems varies greatly, from pairswith helpers-at-the-nest to communal breeders, andmay include younghelpers or post-reproductive ‘grandparents’. That some individuals spend p...
متن کاملIDEA AND PERSPECT IVE The ecology of cooperative breeding behaviour
Sheng-Feng Shen,* Stephen T. Emlen, Walter D. Koenig and Dustin R. Rubenstein Abstract Ecology is a fundamental driving force for the evolutionary transition from solitary living to breeding cooperatively in groups. However, the fact that both benign and harsh, as well as stable and fluctuating, environments can favour the evolution of cooperative breeding behaviour constitutes a paradox of env...
متن کاملWhat drives cooperative breeding?
Cooperative breeding, in which more than a pair of conspecifics cooperate to raise young at a single nest or brood, is widespread among vertebrates but highly variable in its geographic distribution. Particularly vexing has been identifying the ecological correlates of this phenomenon, which has been suggested to be favored in populations inhabiting both relatively stable, productive environmen...
متن کاملC Cooperative Breeding
Cooperative breeding is characterized by a combination of group living and alloparental care, i.e., the care of others’ offspring. Typically, young of previous broods remain in their natal territory and help raising subsequent offspring of dominant breeders. Hence, the characteristic of cooperative breeding is the joint occurrence of delayed dispersal of young with a propensity to help caring f...
