Several evolutionary models of vampire bat food sharing as multi-level selection view them as foraging individually then sharing food at the group-level ( Di Tosto et al., 2007 Foster, 2004 Witkowski, 2007), but this view contrasts with evidence that food-sharing relationships within groups are reciprocal and highly differentiated ( Carter and Wilkinson, 2015 Wilkinson, 1984). The form of social foraging and the scale of competition over resources outside the roost can have implications for the evolution of food-sharing relationships. Socially-hunting species can be placed on a spectrum of resource sharing from individual foragers competing to group-level sharing ( Lang and Farine, 2017). Social foraging can take many forms, from mere aggregations attracted to a common resource to coordinated foraging groups with differentiated roles. Wilkinson (1985) described evidence that mother-daughter pairs co-forage and share wounds, but found no evidence that frequent roostmates forage together. There are also observations of up to four individuals feeding simultaneously from different wounds on the same cow ( Greenhall et al., 1971), or pairs feeding on the same wound ( Greenhall et al., 1971 Wilkinson, 1985). Several authors provide anecdotal evidence for: groups of females apparently flying together, adult females departing roosts in groups of 2-6, and groups arriving together at a pasture, or approaching and circling prey ( Crespo et al., 1974 Greenhall et al., 1971 Wilkinson, 1985 Wilkinson, 1988). For example, foraging with socially bonded roostmates might increase efficiency in searching for prey or feeding from wounds, but it remains unclear if or how vampire bats perform social hunting. However, little is known about if or how cooperative relationships extend beyond the roost. These preferred associations and cooperative interactions occur within the day roost. A particularly clear non-primate example of cooperative relationships providing food occurs in common vampire bats where females regurgitate ingested blood to socially bonded kin and nonkin that failed to feed that night ( Carter and Wilkinson, 2013 Wilkinson, 1984).įood-sharing relationships in vampire bats form as preferred associates escalate social grooming ( Carter et al., 2020). For example, grooming in chacma baboons promotes tolerance during foraging ( King et al., 2011), and vervet monkeys strategically groom individuals that control access to food due to social dominance ( Borgeaud and Bshary, 2015) or an experimentally manipulated ability to access food ( Fruteau et al., 2009). stable preferred associations that involve cooperative investments such as grooming and food sharing. Access to food is therefore one benefit of long-term cooperative relationships, i.e. Emery et al., 2007 Robichaud et al., 1996 Seed et al., 2008), or even give food to less successful foragers (e.g.

Social relationships can determine access to food because closely affiliated individuals can peacefully co-feed at a food patch, hunt together ( Lang and Farine, 2017), cooperatively defend food patches (e.g.

Conversely, shared foraging behaviors might shape how relationships form (e.g. Preferred social relationships can drive foraging decisions (e.g. Socializing and foraging are two key determinants of reproduction and survival that can influence each other in several interesting ways.
