Many birds join cooperative mobbing aggregations and collectively harass predators. Individuals participating in these ephemeral associations benefit by deterring the predator, but also incur energetic costs and increased risk of predation. Ex- plaining the evolution of mobbing is challenging because individuals could prevail by selfishly seeking safety while allowing others to mob. An important step in understanding the evolution of mobbing is to identify factors affecting its expression. The…

Increased risk of predation increases mobbing intensity in tropical birds of French Guiana

Experimental evidence that birds exhibit stronger mobbing responses when the predator is locally abundant, while repeated encounters can be perceived as more dangerous when the predators is rare is provided.

Mobbing behaviour varies according to predator dangerousness and occurrence

Ecological and phylogenetic predictors of mobbing behavior in a tropical dry forest

The results suggest that mobbing behavior is tightly associated with predation risk and the capacity of individual species to find and detect predators, and that functional and phylogenetic features can predict species participation in this complex animal behavior.

Mobbing of the top predator: a correlation between avian community richness and the number of mobbing species

Mobbing is an anti-predator strategy initiated by one or more members of prey species aiming at driving away a predator that is not undertaking an attack. Because of a continuous dispute as to

Mobbing behaviour in a passerine community increases with prevalence in predator diet

This study shows a differential mobbing response of 22 species to the calls from one predator species and underscores the importance of considering seasonal variation in mobbing behaviour.

Threat-sensitive anti-predator defence in precocial wader, the northern lapwing Vanellus vanellus

It is concluded that a single species may exhibit various patterns of temporal variation in anti-predator defence, which may correspond with various hypotheses derived from parental investment theory.

Lions, hyenas and mobs (oh my!)

Whether or not mobbing resulted in acquisition of food from lions was predicted by an increase in the number of mobs formed by the hyenas present, suggesting that cooperation amonghyenas enhances their fitness.

Evolutionary and Ecological Pressures Shaping Social Wasps Collective Defenses

Primary predators of large wasp colonies seem to be highly adapted to resist or avoid aggressive nest defense, such as large birds and mammals, and ants and hornets, and ants.

Understory avifauna exhibits altered mobbing behavior in tropical forest degraded by selective logging

It is found that selective logging altered birds’ predator-mobbing intensity as well as forest structure, and that vegetative changes to canopy and understory were correlated with contrasting responses by the two major bird foraging guilds, gleaning versus flycatching birds.

Interpopulation Comparisons of Antipredator Defense Behavior of the Thorn-Tailed Rayadito (Aphrastura spinicauda)

The lack of variation in nest-defense behavior in the thorn-tailed rayadito provides some support for the multipredator hypothesis, although the high interpopulation gene flow in this species could also contribute to this behavior's maintenance.



Long-lasting mobbing of the pied flycatcher increases the risk of nest predation

The results of the present study show that long-lasting conspicuous mobbing calls may carry a significant cost for the breeding birds.

Responses by breeding birds to heterospecific song and mobbing call playbacks under varying predation risk

Out results suggest that birds exploit heterospecific signals in their decision making but under the constraints of predation risk, but large bird species did not.

Cost of mobbing call to breeding pied flycatcher, Ficedula hypoleuca

The results of the present study indicate that repeated conspicuous mobbing calls may carry a significant cost for birds during the breeding season.

Effects of avian mobbing on roost use and diet of powerful owls, Ninox strenua

The species in this study took a high risk by mobbing a very large predator, but benefited by greatly reducing their chances of predation, thus reducing the chances of an owl being detected by potential mobbers.

The Adaptive Significance of Avian Mobbing V. An Experimental Test of the ‘Move On’ Hypothesis

This paper presents the first experimental study of the effects of mobbing on predators. Two captive little owls Athene noctua and a tawny owl Strix aluco, having stabilized activity patterns and

Interspecific attraction to the mobbing calls of black-capped chickadees (Parus atricapillus)

That significantly more birds approached the speaker and displayed mobbing behavior during the mobbing call playback suggests that black-capped chickadee mobbing vocalizations carry meaning for at least ten other avian species.

Are Blackcaps (Sylvia atricapilla) defending their nests also calling for help from their neighbours?

It is argued that this hypothesis is unlikely to apply to typical avian predators during nest predation acts because these only last for several seconds, and the observed pattern of the positive correlation between the intensity of nest defence and the number of attracted birds is most likely a proximate by-product of the conspicuous nest defence by Blackcaps.
