Strategic 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 کاملCooperative 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 کاملBehaviour: Begging Is a Joint Effort in Banded Mongooses
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.
متن کاملVariable ecological conditions promote male helping by changing banded mongoose group composition
Ecological conditions are expected to have an important influence on individuals' investment in cooperative care. However, the nature of their effects is unclear: both favorable and unfavorable conditions have been found to promote helping behavior. Recent studies provide a possible explanation for these conflicting results by suggesting that increased ecological variability, rather than change...
متن کاملSmelling fit: scent marking exposes parasitic infection status in the banded mongoose
Preference for uninfected mates is presumed beneficial as it minimizes one's risk of contracting an infection and infecting one's offspring. In avian systems, visual ornaments are often used to indicate parasite burdens and facilitate mate choice. However, in mammals, olfactory cues have been proposed to act as a mechanism allowing potential mates to be discriminated by infection status. The ef...
