Acorn woodpeckers are cooperative breeders which live in family groups of up to 12 adults. Analysis of the reproductive success and subsequent survivorship of young within groups indicates that (1) yearly variation in conditions, (2) prior group history, (3) territory quality, and (4) group size all contribute substantially to the variability of these data. Of these, (1) and (2) are the most important. An analysis of covariance of reproductive success versus variables (1) to (4) above indicates… Expand

Estimates of reproductive success for group-living prairie voles, Microtus ochrogaster, in high-density populations
TLDR
Per capita reproductive success increased with group size in food-supplemented populations of prairie voles, and was not due to the presence of additional breeding females since per capita production of offspring decreased in groups with larger numbers of breeding females. Expand
Sociality and cooperative breeding of red-cockaded woodpeckers,Picoides borealis
TLDR
The negative correlation between the efficacy of helping behavior and the helpers' relatedness to the offspring they help rear implies that helpers are least effective in producing offspring which would represent greatest gains to indirect fitness. Expand
Territory Quality and Dispersal Options in the Acorn Woodpecker, and a Challenge to the Habitat-Saturation Model of Cooperative Breeding
TLDR
It is suggested that competition for space may be the outcome of factors that promote philopatry, such as access to a critical resource and/or mutualistic benefits of living in a group and eventually breeding in the natal territory. Expand
The Cooperative Breeding System of the Red‐cockaded Woodpecker
TLDR
The habitat saturation model of the evolution of cooperative breeding is based on selection between the two life-history strategies exhibited by male red-cockaded woodpeckers, and it is suggested that females sometimes are forced from groups by immigrants or other group members. Expand
Cooperative enhancement of reproductive success in white-winged choughs
TLDR
The reproductive success of groups of white-winged choughs from the start of one breeding season to the next over 3 years is traced, highlighting the need to consider the effect of helpers over the entire period of reproduction and care of young, rather than just at fledging. Expand
Breeder age, group size, and fledgling production in the cooperatively breeding Red-cockaded Woodpecker (Dryobates borealis)
ABSTRACT Field studies of the factors that influence reproductive success are crucial to life history theory. We investigate annual fledgling production by the monogamous, cooperatively breeding… Expand
Costs and Benefits of Joint Nesting in the Acorn Woodpecker
The acorn woodpecker (Melanerpes formicivorus) is a cooperative breeder that lives in permanently territorial family groups of 2-15 individuals. Although most groups contain only one breeding female,… Expand
Replacement of breeders and within-group conflict in the cooperatively breeding acorn woodpecker
TLDR
The potential for competition among close kin is high in cooperative species because breeding opportunities are limited and dominance interactions between parents and offspring and among siblings appeared to prevent some individuals from breeding. Expand
The demography and cooperative breeding behaviour of the rufous treecreeper, Climacteris rufa
TLDR
Cooperative breeding in the rufous treecreeper appears to be influenced by habitat saturation and a cost–benefit trade-off between remaining as a helper in high-quality territories and dispersing to poorer- quality territories where reproductive success may be low. Expand
Demography and the Evolution of Cooperative Breeding in the Bicolored Wren, Campylorhynchus Griseus
TLDR
The population consequences of differences suggest that group size is held below its optimum in one habitat by high juvenile mortality, whereas habitat saturation is probably responsible for the fact that about one-third of all groups in the second habitat contain more than an optimum number of members.

Habitat saturation and communal breeding in the acorn woodpecker
TLDR
It is suggested that habitat saturation plays an important role in communal breeding in this species. Expand
ADVANTAGES AND DISADVANTAGES OF BANK SWALLOW (RIPARIA RIPARIA) COLONIALITY
TLDR
It is suggested that reduced predation on eggs and young, resulting from both gr ouLp defense and "selfish herd" effects, is an important advantage of Bank Swallow coloniality. Expand
The Inheritance of Territory in Group-Breeding Birds
TLDR
It is hypothesized in this paper that, in certain species, remaining home and helping represents a strategy used by nonbreeders to inherit the space necessary for breeding. Expand
Demography of the Jungle Babbler, Turdoides striatus
TLDR
There was no significant correlation between group size and breeding success, and there was some indication that larger size may have been correlated with lower fledging success in the spring, which appears to contradict the prediction of kin selection than non-breeding members of the group should make a positive contribution to the reproduction of the closely related breeding pair.

Space competition in the acorn woodpecker: Power struggles in a cooperative breeder
TLDR
Evidence from several sources suggests that irruptions of agonistic behaviour involving large numbers of intruders invading a territory are usually contests among potential immigrants for the opportunity to replace a missing group member (hence, ‘power struggles’). Expand
The Social Organisation of Antelope in Relation To Their Ecology
TLDR
The paper describes different feeding styles among antelope, in terms of selection of food items and coverage of home ranges, and argues that these feeding styles bear a relationship to maximum group size of feeding animals through the influence of dispersion ofFood items upon group cohesion. Expand
Relatedness and Inbreeding Avoidance: Counterploys in the Communally Nesting Acorn Woodpecker
TLDR
Acorn woodpeckers (Melanerpes formicivorus) live in family groups within which more than one female may lay eggs communally in a single nest, ensuring that inbreeding between close relatives is rare. Expand
The Evolution of Group Territorial Behavior and Cooperative Breeding
TLDR
A nonmathematical model is presented which predicts that maximum positive assistance by nonbreeders to the reproductive success of the breeding pair should occur in situations where it would not otherwise increase the fitness of the breeders to allow nonbreeds to remain within their territory.

The relationship of habitat quality to group size in Hall's babbler (Pomastostomus halli)
TLDR
Examining some of the proximate factors that influence flock size in a species of bird with a communal social system found three vegetational indices of home range quality that helped to understand the adaptive aspects of operational altruism in such social systems. Expand
The Auxiliary Social System and Its Effect on Territory and Breeding in Kookaburras
TLDR
The auxiliary system appears to be a long-term adaptation for reducing fertility in accord with longevity incurred from living in the equable Bassian Region, but short-term regulation of the population appears to have been achieved through mortality from asynchronous hatching and the ability of families to rear two broods.
