Communal roosts as structured information centres in the raven, Corvus corax

  author={Jonathan Wright and Richard E. Stone and Nigel Brown},
  journal={Journal of Animal Ecology},
Summary 1. Ravens ( Corvus corax , L.) feed on rich but ephemeral carcasses of large animals. Nonbreeding juveniles forage socially and aggregate in communal winter roosts, which may function as ‘information centres’ regarding food locations. 2. In a large roost in North Wales, regurgitated pellets on the forest floor contained a variety of prey remains, which were more similar for ravens that had roosted close together the same night. 3. Sheep carcasses placed at varying distances from the…

Rich Pickings Near Large Communal Roosts Favor ‘Gang’ Foraging by Juvenile Common Ravens, Corvus corax

This work adapts a general model of juvenile common raven foraging behavior to show formally how the trade off between search efficiency and social opportunity can account for the existence of the alternative social foraging tactics that have been observed in this species.

Common Myna Roosts Are Not Recruitment Centres

The recruitment centre hypothesis did not hold in the study population of mynas, and flock sizes were smallest at the feeding site and larger in the evening than in the morning, but did not coincide with predator activity, information transfer unrelated to food may possibly give rise to the evening aggregations.

Raven Corvus corax ecology in a primeval temperate forest

Several field studies on common ravens Corvus corax were carried out between 1985 and 2004 in Białowieża Primeval Forest (E Poland), one of the best preserved lowland temperate forests in Europe. The

Effect of weather conditions on the communal roosting behaviour of common ravens Corvus corax with unlimited food resources

Examination of roosting times of common ravens in Thuringia, Germany, found flexible time–activity budgets resulting from a superabundant food supply may have enabled ravens to moderate the effects of environmental conditions on arrival times at the preroost and the roost.

Winter Ecology and Spring Dispersal of Common Ravens in Wyoming

Abstract. Numbers of Common Ravens (Corvus corax) have increased in western North America, and these high abundances are the source of problems throughout the species' range. Little is known about

Communal Roost Site Selection in a Neotropical Harvestman: Habitat Limitation vs. Tradition

The roosting behavior of a species of harvestman at a lowland rainforest site in Nicaragua was studied, finding no univariate or multivariate differences between used and unused sites, however, in the characteristics of the trees or microclimate.

Beyond the information centre hypothesis: communal roosting for information on food, predators, travel companions and mates?

A conceptual model, inspired by shorebirds arriving at roosts after foraging on cryptic prey, is proposed to illustrate how testable predictions can be generated and how roost arrival timing may convey inadvertent information on intake rate, prey density, forager state.

Cliffs Used as Communal Roosts by Andean Condors Protect the Birds from Weather and Predators

It is concluded that communal roosting places provide refuge against climate and disturbances such as, for instance, the threats of predators (including humans), and/or from predators or anthropogenic disturbances (threats refuge hypothesis).

Evolution of Communal Roosting: A Social Refuge–Territory Prospecting Hypothesis

The Social Refuge–Territory Prospecting hypothesis provides a unifying explanation for otherwise unexplained paradoxes in the ecology of nonbreeding caracaras, and may be useful in guiding conservation and expanding the understanding of the Ecology of other communally roosting birds.



Can information sharing explain recruitment to food from communal roosts

It is concluded that both information and grouping benefits are likely to underlie communal roosting behavior in my focal system and contrary to assertions in the literature, the opportunity to share foraging information can be sufficient to drive the evolution and maintenance of recruitment to food from communal roops.

Winter foraging at carcasses by three sympatric corvids, with emphasis on recruitment by the raven, Corvus corax

It is concluded that the feeding crowds of ravens consist primarily of juvenile non-breeding vagrants who (unlike some resident adults) roost communally and who vigorously recruit each other in part to neutralize the aggressiveness of resident adults defending prized food bonanzas.

Do common ravens share ephemeral food resources with kin? DNA fingerprinting evidence

It is argued that sharing of food in the study population is unlikely to be a strongly kin-selected trait, but the possibility that kin selection makes some minor contribution to its maintenance is unable to eliminate.

Recruitment to food in black vultures: evidence for following from communal roosts

Common Ravens Are Attracted By Appeasement Calls Of Food Discoverers When Attacked

It is demonstrated through experiments in an aviary complex that begging vocalizations attract other ravens that then learn of new feeding oppor- tunities, and most of the recruitment to carcasses cannot be explained by attraction to local vocalizations alone.

Temporal, spatial and social segregation of red-billed choughs between two types of communal roost: a role for mating and territory acquisition

Choughs from subroosts acquired territories closer to the roost than those who mated in main roosts, supporting the hypothesis that subroOSTs reduce the costs of mating and territory acquisition.

Does the early Common Raven get (and show) the meat

In the forests of western Maine, Common Ravens (Corvus corax) aggregate in large crowds at feeding bonanzas such as carcasses (Heinrich 1988a). A variety of evidence from field observations (Heinrich

On the evolution of delayed recruitment to food bonanzas

A game-theoretic model used to explore the logic of immediate versus delayed recruitment demonstrates that either status enhancement or the posse effect may alone suffice for the evolution of delayed recruitment to food bonanzas via mutualistic information sharing at communal roosts.


It is concluded that birds depending on spatial-concentration effects occasionally may forage more success- fully than noncommunally roosting individuals, but those that form foraging groups do best.
