Allopreening is a widespread but little-studied phenomenon in birds and is particularly prevalent in species where individuals are forced into close proximity. Such a situation facilitates the transfer of ectoparasites between individuals and allopreening has therefore been proposed to serve a hygienic function. In addition, allopreening might theoretically play a role in social communication. Green woodhoopoes (Phoeniculus purpureus) are cooperatively breeding birds that roost communally every… 
Is Allopreening a Stimulus-Driven Defense Against Ectoparasites?
TLDR
A laboratory experiment using wild-caught rock pigeons and captive pigeons revealed a negative correlation between allopreening and self-preening rates, which is consistent with a programmed response that occurs independently of parasite load.

TLDR
The different patterns of allopreening observed within buff-breasted wren families suggest the strategic use of allogrooming, possibly for the maintenance of long-term partnerships and in exchange for social benefits from offspring.
Post-allogrooming reductions in self-directed behaviour are affected by role and status in the green woodhoopoe
TLDR
It is shown that, in cooperatively breeding green woodhoopoes Phoeniculus purpureus, involvement in allogrooming is followed by a reduction in self-grooming by both recipients and donors, but that the former exhibit a greater decrease.
Different patterns of allopreening in the same‐sex and opposite‐sex interactions of juvenile large‐billed crows ( Corvus macrorhynchos )
TLDR
The results suggest that the social function of allopreening in juvenile crows differs depending on the sex composition of the dyad, functioning as a dominance signal for same‐sex dyads, and serving a social bonding function for opposite‐ sex dyads.
Why preen others? Predictors of allopreening in parrots and corvids and comparisons to grooming in great apes
TLDR
The hypothesis that allopreening in corvids and parrots helps maintain social bonds with an individual's most important social partners is supported, showing some similarities to allogrooming in primates.
Does allopreening control avian ectoparasites?
TLDR
The data suggest that allopreening may be a more important means of ectoparasite defence than self-preening when birds live in groups, and have important implications for the evolution of social behaviour.
Social Grooming in the Brown-Headed Nuthatch May have Expanded Functions
TLDR
Observations of allopreening in Sitta pusilla (Brown-headed Nuthatch) are described where sex, age, and kin relationships were known for the individuals performing the behavior, suggesting the behavior may have expanded functions.
Type of threat influences postconflict allopreening in a social bird
Fitness increases with partner and neighbour allopreening
TLDR
It is suggested that altruistic behaviour has long-term benefits for the survival of the offspring when living in a crowded neighbourhood, and allopreening may function as a reciprocal stress reducer, to decrease the likelihood of fights and associated breeding failure.
New Record of Allopreening Between Black Vultures (Coragyps atratus) and Crested Caracara (Caracara plancus)
TLDR
New records of allopreening involving black vultures and crested caracaras involving these species in the Brazilian savanna are described.

Evidence for an important social role of allogrooming in a platyrrhine primate
TLDR
Evidence is provided that allogrooming in this platyrrhine species serves an important social function, as has been demonstrated for catarrhine primates, by the close relationship between allogsrooming, the social system and coalition formation and the changes in quantity and direction of grooming in response to oestrous behaviour and to the birth of infants.

Communal cavity roosting in green woodhoopoes: consequences for energy expenditure and the seasonal pattern of mortality
TLDR
It is reasoned that birds in depressed body condition will be unable to thermoregulate at low ambient temperatures, but that they can do so when roosting in cavities with conspecifics, and the energetic benefits of Green Woodhoopoes' communal cavity-roosting behavior are examined.
Bill dimorphism and foraging niche partitioning in the green woodhoopoe
TLDR
Cooperative breeding green woodhoopoes, Phoeniculus purpureus, forage mainly as close-knit groups, creating opportunities for intrasexual and intersexual foraging competition and support of the specialization hypothesis.
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.
Bowing and allopreening of captive Jackdaws Corvus monedula
TLDR
It is suggested that Bowing here was used as intimidation rather than ‘solicitation’ or appeasement, and that allopreening and Bowing function in confirming relationships and in conveying information about relative status to other members of the group.
Conditional allogrooming in the herb-field mouse
TLDR
Allogrooming is suggested to be the predominant premating mechanism in the herbfield mouse in those species where the demand for mating by males is far greater than that offered by females, in other words where females may select mates.
Allopreening as Agonistic Behaviour
TLDR
An examination of the known incidence of allopreening, which has been summarised for the Families concerned, shows that certain characters reoccur in association with it and may be factors determining its appearance.
Aggression, ectoparasitism, and other possible costs of prairie dog (Sciuridae, Cynomys spp.) coloniality.
TLDR
It is concluded that there are probably several costs associated with prairie dog coloniality, that the severity of some of the costs correlates positively with colony or ward size for both White-tails and Black-tails, and that some ofThe costs are probably more pronounced for Black-tail than for White-tail.
Ectoparasites reduce long-term survival of their avian host
TLDR
It is suggested that future studies of ectoparasitism should consider the parasites’ effect on annual survival of adult hosts and suggest that all birds in the population were at potential risk of suffering parasitism and the resulting reductions in survivorship.
