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
Local predation pressure predicts the strength of mobbing responses in tropical birds
Results support the ecological constraints model and provide strong evidence that intense predation pressure increases the expression of cooperative mobbing in tropical birds.
Seasonal variation in mobbing behaviour of passerine birds
A previously unsuspected level of complexity in the use of mobbing calls is demonstrated at the heterospecific communication level and it is found that mobbing intensity was greater in autumn than in spring.
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.
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.
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
Exposure affects the risk of an owl being mobbed / experimental evidence
The results of the first experimental study investigating to what degree roost exposure influences the risk of being mobbed, and the intensity of a mobbing incidence once initiated suggest that an owl may minimize the mobbing rate by reducing the encounter rate with potential mobbers through its choice of roost.
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.


Seasonal Variation and Function of Mobbing and Related Antipredator Behaviors of the American Robin (Turdus migratorius)
It is suggested that mobbing and attacking are beneficial for robins only when birds are confined to territories or home ranges, and the presence of young on territories further increases the amount of parental mobbing.
Variability in the Responses of Black-Billed Magpies To Natural Predators
It is suggested that although parental investment theory may be basically correct in predicting that young increase in value to their parent as they approach independence, a variety of other factors may affect anti-predator behavior, such as the types of predators likely to be encountered and the relative danger they pose to different age classes.
Nest defence in the American goldfinch
It is suggested that reduced predation on eggs and young, resulting from both gr ouLp defense and "selfish herd" effects, is an important advantage of Bank Swallow coloniality.
Seasonal variation, and associated energetic implications, in the hunting behaviour of the Kestrel
There is seasonal variation in the extent to which Kestrels perch-hunt versus flighthunt. This seems to be related to the energetic 'costs' of each method as the ground vegetation changes seasonally.

Habitat utilisation and the prey taken by Kestrels in arable fenland
These Kestrels made 70% of their strikes over grass which comprised only 17% of the study area. This reflected their mainly mammalian diet.

A model is presented to account for the natural selection of what is termed reciprocally altruistic behavior. The model shows how selection can operate against the cheater (non-reciprocator) in the
