Honest begging in the blue-footed booby: signaling food deprivation and body condition

  title={Honest begging in the blue-footed booby: signaling food deprivation and body condition},
  author={Emma Villase{\~n}or and Hugh Drummond},
  journal={Behavioral Ecology and Sociobiology},
To determine whether solicitation by blue-footed booby chicks accurately encodes their need for food, we independently manipulated the body condition and recent food ingestion of singleton chicks and recorded three measures of begging. Variations in the three measures of begging covaried only partially, but in general, chicks begged more intensely when they were in poor body condition and also when suffering recent food deprivation. Effects of body condition and recent food deprivation on…

Condition-Dependent Begging Elicits Increased Parental Investment in a Wild Bird Population
The longer-term changes in nestling condition, begging, and food provisioning suggest that begging ultimately signals offspring quality to elicit increased investment, thereby enhancing offspring survival.
Effects of variation in nestling hunger levels and begging on the provisioning behavior of male and female Eastern Phoebes (Sayornis phoebe)
It is suggested that nestling begging is an honest signal of hunger and parents respond to variation in nestling begged by adjusting their provisioning behavior, suggesting a trade-off between investment in current and future reproduction.
The Impact of Ambient Noise on Eastern Bluebird (Sialia sialis) Nestling Begging
A growing body of evidence suggests that environmental ambient noises, particularly anthropogenic noises from urbanization, impact animal acoustic systems. In this study, I tested whether eastern
Efficiency and Significance of Multiple Vocal Signals in Sibling Competition
Young animals actively and differentially use multiple signaling components to compete with their siblings over parental resources and test the hypothesis that the most efficient signal to deter opponents should be the one that most honestly reveals motivation to compete.
Parent-offspring conflict, sibling rivalry and coadaptation
Conflict arises in families because of a fundamental relatedness asymmetry. When parents are equally related to all offspring they would prefer to divide resources equitably among young. However,
The pre-reproductive period in a tropical bird: parental care, dispersal, survival, and avian life histories
The results indicate that parents provide greater care after fledging and this extended care likely increased offspring survival, and the findings of extended postfledging parental care and higher post-fledges survival compared to northern hemisphere species have implications for understanding latitudinal variation in reproductive effort and parental investment strategies.
Parasitism, family conflict and breeding success
It is demonstrated that parasitism can be a key component, previously overlooked, of reproductive performance in seabirds, a group that plays an important ecological role as apex predators and thus indicator species of the marine environment.


Begging as graded signals of need for food in young ring-billed gulls
The effects on begging of short-term food deprivation ('hunger') and long-term reduction in body condition under controlled laboratory conditions in ring-billed gulls, Larus delawarensis, appear to agree with the design requirements of a homeostatic control system and with predictions of current game-theoretic models of honest signalling.
Begging tactics of nestling yellow-headed blackbirds, Xanthocephalus xanthocephalus , in relation to need
In yellow-headed blackbirds, even when nestmates have unequal competitive abilities, begging can carry information about nestling long-term need for food, and when hunger level was controlled, males and chick in poor condition begged more than females and chicks in good condition.
Begging in the absence of sibling competition in Wilson’s storm-petrels, Oceanites oceanicus
It is found that chicks conveyed information about their current body condition by begging, demonstrating that the begging system can work in the absence of nestling competition.
Begging Versus Aggression in Avian Broodmate Competition
Observations of boobies and diverse species suggest that aggression limits the effectiveness of begging by subordinate young by confining its timing, location or form.
Mouth colour is a reliable signal of need in begging canary nestlings

It is reported that mouth colour functions as a signal of need in canary nestlings, in the days immediately following hatching, and is consistent with recent models of the resolution of parent-offspring conflict.
Chick hunger and begging affect parental allocation of feedings in pigeons
Chick begging as a signal: are nestlings honest?
The view that begging is a reliable signal of individual chick state and does not involve responses to the effort of nest mates is supported.
Parent-offspring cooperation in the blue-footed boody (Sula nebouxii): social roles in infanticial brood reduction
Reproduction in the blue-footed boody was examined for evidence of parent-offspring conflict over infanticidal reduction of the brood, and provisional tolerance of the junior chick by its underweight senior sib is consistent with “self-sacrifice” to increase the latter's inclusive fitness.
Begging affects parental effort in the pied flycatcher, Ficedula hypoleuca
It is demonstrated that pied flycatcher nestlings that beg more are able to increase parental provisioning rates over the major part of the nestling period, thus potentially competing with future siblings.
