One foraging strategy that scavengers can employ to discover unpredictable food sources is to associate directly with predators who inadvertently provide food. The common raven, a well known feeding generalist, is also a prominent scavenger of wolves' kills and is found to be in close association with this predator. We tested the hypothesis that ravens preferentially associate with wolves in winter as a kleptoparasitic foraging strategy. The presence, absence and behaviour of ravens was… 
Population responses of common ravens to reintroduced gray wolves
TLDR
Whether subsidies provided through wolves are a limiting factor for raven populations in general and how the wolf reintroduction to Yellowstone National Park in 1995–1997 affected raven population abundance and distribution on the Yellowstone's Northern Range specifically are investigated.
Gifts of an enemy: scavenging dynamics in the presence of wolves (Canis lupus)
Carrion represents an important resource for carnivores. Examining competition for carrion in a risk–reward framework allows for a better understanding of how predator guilds compete for and benefit
Foraging and feeding ecology of the gray wolf (Canis lupus): lessons from Yellowstone National Park, Wyoming, USA.
TLDR
As patterns of wolf density, prey density, weather, and vulnerability of prey change, in comparison with the conditions of the study period described here, it is predicted that there will also be significant changes in wolf predation patterns and feeding behavior.
Winter population dynamics between the Eastern Wolf (Canis lycaon) and the Common Raven (Corvus corax) in Algonquin Park, Ontario
The eastern wolf (Canis lycaon) is important to the Algonquin Provincial Park ecosystem through its top-down influences on the food web. While previous research in Yellowstone National Park has shown
Does Grey Wolf Presence Affect Habitat Selection of Wolverines?
Scavengers can improve their foraging possibilities by associating with predators that provide food. Therefore, the presence of grey wolves (Canis lupus) may increase scavenging opportunities for
Trophic facilitation by introduced top predators: grey wolf subsidies to scavengers in Yellowstone National Park
TLDR
It is demonstrated that wolves increase the time period over which carrion is available, and change the variability in scavenge from a late winter pulse dependent primarily on abiotic environmental conditions to one that is relatively constant across the winter and primarily dependent on wolf demographics.
Raven scavenging favours group foraging in wolves
Food calling in wild ravens ( Corvus corax ) revisited: Who is addressed?
Numerous birds and mammals use vocal signals to advertise feeding opportunities but often such signals vary with individual and contextual factors. Non-breeding ravens call at food that is difficult
Social scavenging by wintering striated caracaras (Phalcoboenus australis) in the Falkland Islands
TLDR
It is found that food obtained per individual was greater toward the beginning of carcass availability, when competition was fierce; that vocalizations, by birds at and approaching the carcass, preceded periods of faster group formation; and that on average birds would approach a speaker playing conspecific calls more closely than one playing a control recording.

TLDR
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.
Feeding success in African wild dogs : does kleptoparasitism by spotted hyenas influence hunting group size ?
TLDR
It is proposed that kleptoparasitism by spotted hyenas would have placed a major constraint on the ability of individual wild dog packs to recover from episodic disasters.
Foraging ecology of coyotes (Canis latrans): the influence of extrinsic factors and a dominance hierarchy
TLDR
During times of deep snow and high carcass biomass, pups fed less on carcasses and hunted small mammals more than alpha and beta coyotes, and apparently were restricted by older pack members from feeding on a carcass.
Raven roosts are mobile information centres
Vagrant, non-breeding common ravens,Corvus corax, inhabiting the forested mountains of Maine are specialized to feed on rich but ephemeral carcasses of large mammals during the harsh winter months.
Food acquisition by spotted hyaenas in Etosha National Park, Namibia: predation versus scavenging
Summary Feeding ecology of spotted hyaenas was studied in central Etosha National Park, Namibia to contribute to the definition of the hyaena's niche as a predator/scavenger, and to determine if

Factors influencing the hunting success of an African wild dog pack
TLDR
Two ways in which wild dogs may benefit from communal hunting are suggested, which increased the range of prey species available to the pack and reduced interspecific competition from spotted hyaenas, Crocuta crocuta, through improved defence of carcasses.
Optimal hunting group size: the need for lions to defend their kills against loss to spotted hyaenas
TLDR
Preliminary evidence that kleptoparasitism by spotted hyaenas may influence optimal hunting group size of lions is presented, showing that at Savuti, where there was a shortage of adult male lions, the groups of female and subadult lions lost almost 20% of their food to hyAenas.
Limitation of African Wild Dogs by Competition with Larger Carnivores
TLDR
Data suggest that competition with spotted hyaenas may limit or exclude wild dogs when hyaena density is high, and competition with lions appears less intense, but direct predation by lions on wild dogs is important.
