Abstract Common guillemots characteristically nest in dense groups in close bodily contact. Behavioural adaptations to high density nesting were examined by comparing (i) the guillemot with the closely related razorbill, which nests at lower densities, and (ii) the behaviour of guillemots nesting at different densities. Guillemots perform active and passive appeasement displays more frequently at higher densities and more frequently than razorbills. Guillemots return to the colony 4 months… 
Social interactions among breeding Brünnich's Guillemots Uria lomvia suggest constraints in relation to offspring vulnerability
TLDR
The amount of aggression increased significantly at the time of hatching, perhaps in response to the reduced risk of breeding failure through dislodgement of a chick, compared with an egg, and allopreening followed an inverse trend, falling significantly after the day of hatch.
Behavioural and physiological responses of breeding common murres (Uria aalge): exploring inter-annual variability within individuals
TLDR
The results suggest that murres were stressed during early chick rearing in 1999, supporting the view that breeding conditions were less favourable in that year, and seabirds relying on capelin in the Northwest Atlantic are experiencing highly variable breeding conditions.
Survival and non‐breeding of adult Common Guillemots Una aalge
TLDR
It appeared that non-breeding in Common Guillemots on the Isle of May was socially induced with most cases occurring after an individual had lost its site.
Assessment of Social Attraction Techniques Used to Restore a Common Murre Colony in Central California
Abstract Colonial seabirds such as alcids often do not rapidly recolonize former breeding habitat following extirpation of nesting colonies. Social attraction (e.g., use of decoys, recorded
Non‐random, intra‐colony distribution of bridled guillemots Uria aalge
Within the Common guillemot Uria aalge colony, at the Gannet Clusters, Labrador, Canada, there was no evidence of heterogeneity in the proportion of bridled birds in different parts of the colony.
Influence of group size and habitat type on reproductive success in Common Murres (Uria aalge)
TLDR
As a function of size, nesting colonies dilute the risk of predation and also may provide members with early warning of predator presence, and whether colonial nesting confers advantages on the adults, with respect to predation, depends on the numerical response of predators to colony size and location.
Use of appeasement display and recruitment by an adult Striated Caracara (Phalcoboenus australis) to overcome territorial defense
ABSTRACT Adult animals across many taxa use appeasement signaling to minimize or avoid costly conflict in social settings by jointly communicating their consent to defer and an interest to remain.
Sex‐biased aggression and male‐only care at sea in Brünnich’s Guillemots Uria lomvia and Razorbills Alca torda
TLDR
In Brunnich's Guillemots and Razorbills, there was a similar male bias in morphology and behaviour that is consistent with male parents being more capable of protecting their chick, a probable advantage to chick survival during the uniparental care phase of some Charadriformes.
POSTFLEDGING OCCUPANCY OF BREEDING SITES BY FEMALE COMMON MURRES (URIA AALGE)
TLDR
It is concluded that successful males and females were maximizing time spent occupying the best breeding sites, even to the extent that only one adult took the chick to sea to complete its development.
Factors influencing subcolony colonization and persistence in a colonial seabird, the common murre Uria aalge
TLDR
The results support the theory that the proportion of the entire murre popula- tion that attempts to breed in a given year is higher in years with favorable environmental conditions prior to the breeding season.

Breeding biology and survival of guillemots (Uria aalge)
TLDR
The aims of the study were to examine some population parameters of the Common Guillemot Uria aalge on Skomer Island, Wales, where a decline in numbers has occurred, and to examine a number of different aspects of the birds' breeding biology, including the adaptive nature of high density nesting.
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.

TLDR
For several years the study of social behavior has been undergoing a revolution with far-reaching consequences for the social and biological sciences, partly due to growing acceptance of the evidence that the potency of natural selection is overwhelmingly concentrated at levels no higher than that of the individual.
