Behaviour: Begging Is a Joint Effort in Banded Mongooses
نویسنده
چکیده
Lack of competition for food items in banded mongoose litters allows pups to benefit from more demanding siblings, suggesting that in this species begging may not be entirely selfish.

Cooperative Begging in Banded Mongoose Pups
Vivid begging displays are common in species with parental care [1, 2]. They are usually seen as the way that rival offspring selfishly compete over parental investment [3], and individuals are expected to respond to the begging of rivals by increasing their own begging intensity [4, 5]. Here I show the opposite - that potential rivals gain direct benefits from begging by littermates, so that b...
متن کاملStrategic adjustment of begging effort by banded mongoose pups.
Variation in the intensity of conspicuous displays raises three basic questions: (i) the relationship between internal state and display intensity, (ii) the relationship between display intensity and receiver response, and (iii) the effect of variation in receiver responsiveness on signaller behaviour. Here, I investigate the interaction between pups and helpers in the communally breeding bande...
متن کاملBanded mongooses avoid inbreeding when mating with members of the same natal group
Inbreeding and inbreeding avoidance are key factors in the evolution of animal societies, influencing dispersal and reproductive strategies which can affect relatedness structure and helping behaviours. In cooperative breeding systems, individuals typically avoid inbreeding through reproductive restraint and/or dispersing to breed outside their natal group. However, where groups contain multipl...
متن کاملDiagnosis and Implications of Mycobacterium Bovis Infection in Banded Mongooses (mungos Mungo) in the Kruger National Park, South Africa.
Bovine tuberculosis (bTB) was first diagnosed in the Kruger National Park (KNP) in 1990. Research has since focused on the maintenance host, the African buffalo ( Syncerus caffer ) and clinically affected lion ( Panthera leo ). However, little is known about the role of small predators in tuberculosis epidemiology. During 2011-12, we screened banded mongooses ( Mungos mungo ) in the bTB high-pr...
متن کاملHow do banded mongooses locate and select anvils for cracking encased food items?
Banded mongooses (Mungos mungo) extract encased food items by throwing them against anvils. Observations indicate that their chosen anvils are generally hard enough to crack open casings, suggesting an understanding of the physical properties that render an anvil suitable for cracking. We report results from two field experiments investigating spatial and physical aspects of anvil selection in ...
