Behaviour: 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 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 کاملImitation and Traditions in Wild Banded Mongooses
Evidence has accumulated in recent years indicating that traditions are not a unique feature of human societies but may be common in primates and some other mammals. However, most documented cases remain contentious because observational studies of free-living animals suffer from interpretive weaknesses, whereas social diffusion experiments performed in captivity may not reflect conditions foun...
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 کاملReproductive competition triggers mass eviction in cooperative banded mongooses.
In many vertebrate societies, forced eviction of group members is an important determinant of population structure, but little is known about what triggers eviction. Three main explanations are: (i) the reproductive competition hypothesis, (ii) the coercion of cooperation hypothesis, and (iii) the adaptive forced dispersal hypothesis. The last hypothesis proposes that dominant individuals use e...
