357:: Begging incurs a growth cost in canary chicks. When the brood is very hungry, begging becomes a form of scramble competition whereby offspring jostle to be closest to the feeding adult. When the brood has recently been fed, adults instead actively choose offspring to feed because begging reliably signals nestling hunger. Experimental manipulations of begging behaviour and food reward show that excessive begging retards growth, both immediately and in the longer term, and the impact of the manipulation is greatest in chicks with the highest potential daily mass gain. Furthermore, the greater the difference in begging intensity between siblings during the experiment, the greater the difference between them in the mass lost as a result of metabolic expenditure. This growth cost of begging can be interpreted as a fitness cost, because daily mass gain is strongly correlated with the likelihood of survival to independence. Begging may incur an additional indirect growth cost through its actions on digestive efficiency. Chicks that are forced to beg excessively produce a greater number of fecal sacs, although not more fecal waste in total, than their less exercised siblings. The faster rate of fecal sac production may indicate an increased digesta throughput rate, which is known to reduce digestive efficiency.
436:: Banded mongooses live in large family groups of 5–75. Females give birth in synchrony, producing large communal litters which remain in dens for 3–4 weeks. When pups emerge from the den, they spend 3–5 days approaching different helpers, after which individual pups form stable associations with a single adult helper (their "escort") and remain associated with that animal until independence (approximately 9–13 weeks). During a foraging session, pups follow escorts closely (usually within 10 cm), begging constantly with a high-pitched, bird-like chirp (average call rate = 34.4 calls/min). Packs forage as a cohesive unit, concentrated within 15–20 m, so all escorts are exposed to begging by the whole litter. Pups receive their food almost exclusively from their escorts. Switching between escorts is rare and lasts for only a single day before returning to the original escort. Escorts do not feed pups associated with another adult. Begging behavior in mongooses is unusual in that it is cooperative. Escorts are influenced by the total signal emanating from the litter, so that pups who beg at low rates receive more food as litter size increases. Pups increase their begging when litters are reduced or littermates beg at low rates.
195:) show a ritualised form of begging behaviour which apparently functions as communication of social stability rather than soliciting food. Pack members use body language to show submission to a dominant dog and avoid conflict. They roll over on their bellies or wag their tails. Other signs of submission or appeasement include exposing the throat and food-begging, or licking the corners of the dominant dog's mouth. Pack members show submission towards the alpha female by lying down to “nurse” from her. When two wild dogs meet, they display such submission to one another, muzzle licking, whining, and even regurgitating food to the other. African wild dogs rarely fight over food. If two wild dogs have a piece of food that they both want, rather than inflict injuries upon the other, they will practise "aggressive begging", where they will flatten their ears, curl their lips, lower their front-quarters, curl their tail over their back, and try to crawl under the other wild dog.

534:: Larval burying beetles beg visually, making a waving motion when their parents arrive. When parent beetles lay eggs, they provide a dead animal to nourish the young. As the eggs hatch and larvae grow, the parents feed their brood with regurgitated carcass. The costs of begging by these larvae have been investigated. Begging behavior was controlled by the presence or absence of a dead parent, simultaneously with the opportunity to self-feed through the presence or absence of food. The presence of a dead parent stimulated larval begging, whereas larvae never begged when the dead parent was absent. However, the presence or absence of a dead parent had no effect on larval growth. Likewise, the interaction between the presence or absence of food and the presence or absence of a dead parent had no effect on growth. The authors concluded that there was no evidence of either a growth cost or an
423:: When meerkat pups begin accompanying the group during foraging, they beg food from older group members, who dig up prey items. The probability of a prey item being fed to a pup shows a positive relationship with prey size and a negative relationship with pup distance. Meerkats apparently follow a "feed the nearest pup rule" and are more likely to feed the nearest pup if it is hungry. Hungrier pups beg more and follow older group members more closely. Adult meerkats preferred to provision speakers playing back recordings of two pups begging alternately to recordings of the same two pups begging simultaneously. This indicates that meerkat pups avoid some of the costs of direct competition incurred by an escalation of begging as other pups beg, by begging in gaps between the bouts of others or avoiding littermates.
670:), nestlings vocalize in the presence but also in the absence of the parents. The "sibling negotiation hypothesis" proposes that offspring use each other's begging vocalization as a source of information about their relative willingness to contest the next prey item delivered. This predicts that the more hungry nestling will contest the next item delivered while the less hungry one will retreat to avoid injuries and/or save energy. Nestling barn owls refrain from vocalization when a rival is more hungry, but escalate once the rival has been fed by a parent, and refrain from and escalate vocalization in enlarged and reduced broods. Thus, when parents are not at the nest, a nestling vocally refrains when the value of the next delivered prey item will be higher for its nest-mates.
351:: Nestlings giving repeated begging calls could enable predators to more easily locate the nest. This has been tested by comparing predation rates at artificial nests with and without playbacks of bird begging calls. In trials where tapes were played in an artificial nest with quail eggs, these nests were destroyed by predators before nearby “quiet” nests. Ground-nesting birds are at a greater risk to predation than tree-nesting birds; nestlings of these species have higher frequency begging chirps which travel less distance than lower frequency calls which could reduce their vulnerability to predators. Another behavioral adaptation is that when a nest is in danger, parents give alarm calls which temporarily stop the begging calls of the nestlings.
131:
distribute food accordingly. Offspring want to get as much of the food as possible, so they will want to exaggerate their signals to gain more investment from their parents. However, this conflict is resolved by the cost of excessive begging. Not only does excessive begging attract predators, but it also retards chick growth if begging goes unrewarded. Thus, the cost of increased begging will enforce offspring honesty. A weaker nestling might easily change the intensity at which it begs, but a stronger nestling which is hungry and begging can push to the front of the nest where the parent is.
638:) increase begging indicating that juvenile hormone in insects could have a similar function to that of testosterone and corticosterone in birds. Elevated juvenile hormone levels have a negative effect on larval growth regardless of whether larvae forage by begging or by self-feeding. This shows that the effects of juvenile hormone on larval growth are independent of the effects on begging, suggesting that the mechanisms by which juvenile hormone affects offspring growth in insects differ from those by which testosterone and corticosterone affect growth in birds.

315:). The mouths of canary nestlings are relatively unusual in that, following the onset of each begging bout, they exhibit a rapid change in color intensity. Changes in mouth color accurately reflect a nestling's state of need: the more food-deprived the chick, the more intensely coloured its mouth. In controlled experiments with two nestlings, parents were offered the opportunity to choose which nestling to feed. When the mouth color of one offspring was artificially reddened using food coloring, parents gave it more food.

adult may feed its offspring at this point or run off, pursued by the begging chicks, which it stops intermittently to feed. Chases are almost absent in one-chick broods, or situations in which one sibling is removed from the crèche and only the remaining sibling begs for food. Feeding chases therefore appear to separate offspring in two-chick broods, so parents can feed them more efficiently. Parents start to run as a direct consequence of the distance between siblings and stop as soon as siblings become separated.
345:) energetic expenditure also increases by a similar fraction during begging, but because other forms of exercise incur greater metabolic costs, begging was interpreted to be relatively cost-free in this species. However, the evidence for cheap begging stems entirely from experiments in which chicks were allowed to beg at an intensity of their own choice. Measuring expenditure in this way certainly documents the effort involved in begging, but it does not measure cost, as specified theoretically.

Furthermore, nutritional experiments show that larvae exhibited pecking more frequently when their nutrient status is lower; hence, pecking may be an honest signal of larval hunger status.
263:
Acoustic cues are incredibly important in recognizing chicks. Acoustic cues work over long and short distances, as well as for individual recognition. Birds beg more intensely when they are hungry even though it expends more energy. Larger birds are able to beg longer and expend more calories. Therefore, they are fed more and continue to grow larger.
333:: During begging, nestlings stretch their necks and bodies, gape, and flap their wings. The vigor of these movements indicate that begging may be energetically costly to the individual, however, evidence for this is contradictory. When energetic expenditure was measured in begging tree swallow chicks it was found to be 1.27 or 1.28 times the
