Arabian babblers are cooperatively breeding birds living in groups, whose members defend group territories (Zahavi 1974). Babblers in a particular group typically roost huddled together in a linear array along the branch of a tree, usually Acacia tortillis or Zizyphus spinoeristae. Previous observations had determined that older male birds tend to occur on the outside of roosts (Zahavi 1990). In the present study, we investigated this phenomenon in more detail. The study was carried out between… 
Social ordering of roosting by cooperative breeding buff-throated partridges Tetraophasis szechenyii
TLDR
For buff-throated partridges, it is suggested that while structuring of communal roosts confers the greatest energy benefits and protection from predators to young birds, helpers, rather than the breeding male, may face higher costs in terms of lookout and thermoregulation.
Communal roosting shows dynamics predicted by direct and indirect nepotism in chestnut-crowned babblers
TLDR
It is shown that immigrant females settle in the communal roosts later than nutritionally independent natal females and may occupy peripheral positions in roosting huddles of the cooperatively breeding chestnut-crowned babbler (Pomatostomus ruficeps) using a remote PIT-tag system.
Competing for position in the communal roosts of long-tailed tits
TLDR
The results show that long-tailed tits compete for inner positions within communal roosts, and that an individual's dominance status within a flock influences the outcome of this competition.
SOCIAL STRUCTURE OF ANDEAN CONDOR ROOSTS: INFLUENCE OF SEX, AGE, AND SEASON
Abstract We examined how Andean Condors (Vultur gryphus) segregate by sex and age in summer and autumn at a communal roost in the Patagonian Andes. Preferred roosting places received earlier sun at
Factors influencing overnight loss of body mass in the communal roosts of a social bird
TLDR
It is concluded that long-tailed tits mitigate the costs of surviving the night by roosting communally, but the benefits gained vary in relation to position within the roost, explaining previous observations of competitive interactions during roost formation.
Dominance, not kinship, determines individual position within the communal roosts of a cooperatively breeding bird
TLDR
The effect of kinship on social interactions appears to be less important than the effects of other factors, possibly due to the complex kin structure of winter flocks compared to breeding groups.
Family living among birds
TLDR
The option of gaining inclusive fitness from providing alloparental care is not open to the offspring among single-brooded species until after they have survived a non-breeding season, rather indicating kin cooperation returning enhanced survival prospects from general group living effects as a more immediate factor selecting for family cohesion.

Abstract Five aspects of intra-group behaviour among wild jungle babblers were analysed in relation to the age, sex and breeding status of the participants. The amount of participation in
Differences in the ages, sexes and physical condition of Starlings Sturnus vulgaris at the centre and periphery of roosts
TLDR
The effects of age, sex and physical condition on the structure of Starling roosts were investigated and it was found that the dispersion of different age and sex categories was heterogeneous.

The evolution of a communication system depends on the existence of individuals which gain from it, that is the senders of the signals and their receivers. These two share a common interest about

TLDR
A genetical mathematical model is described which allows for interactions between relatives on one another's fitness and a quantity is found which incorporates the maximizing property of Darwinian fitness, named “inclusive fitness”.

It is suggested that characters which develop through mate preference confer handicaps on the selected individuals in their survival. These handicaps are of use to the selecting sex since they test
