Habituation to human disturbance is faster in urban than rural house sparrows

The findings suggest that the reduced fear of urban animals is the result of behavioral plasticity, whereas there is no evidence for their higher intrinsic boldness as predicted by differential colonization and local adaptation.

Effect of human recreation on bird anti-predatory response

It is found that human frequentation had a distinct effect on bird escape responses, with shorter FIDs in forests more-heavily frequented by humans than in forests rarely visited by humans.

Differing nest-defence behaviour in urban and rural populations of breeding Burrowing Owls

The role of behaviour is highlighted in explaining the ability of Burrowing Owls to live in a range of habitats, including successfully breeding in urban areas, and the importance of breeding stage on behavioural traits is emphasised.

Increased behavioural responses to human disturbance in breeding Burrowing Owls Athene cunicularia

The results suggest that different domains of behaviour (aggression versus fear) may respond differently to human disturbance, and highlight the importance of quantifying a wide range of behavioural acts as indicators of bird stress in studies of anthropogenic impact.

Urban fox squirrels exhibit tolerance to humans but respond to stimuli from natural predators

The results indicate that urban squirrels did perceive and assess risk to the natural predator appropriately despite exhibiting increasedolerance to humans, and provide little support for the hypothesis that increased tolerance to humans causes animals to lose their fear of natural predators.

Eastern Grey Kangaroo (Macropus giganteus) Vigilance Behaviour Varies between Human-Modified and Natural Environments

This is the first study to compare the vigilance behaviour between urban and non-urban populations of a large mammal across regions, giving the first insight into how kangaroos adapt their behaviour in urban environments.

Burrowing owl nest distribution and density in relation to urban development

The results indicate that, unlike many raptors that are negatively affected by urbanization, burrowing owls may not be adversely impacted by nesting in areas with moderate levels of urban development.

Leukocyte profiles and body condition of free-living Burrowing Owls (Athene cunicularia) from rural and urban areas in the Argentina Pampas

Chicks showed higher relative leukocyte counts than adults, which may be associated with ontogenetic development and immune system activation processes, and no significant differences in these parameters between individuals from rural and urban areas were found.

Individual variation in tolerance of human activity by urban Dark-eyed Juncos (Junco hyemalis)

Overall, the behavioral patterns exhibited by this urban population of juncos is more supportive of in situ evolution of tolerance than either being a biased sample from an ancestral non-urban population or intrinsic behavioral plasticity that produces a uniform adjustment to urban life.



High individual consistency in fear of humans throughout the adult lifespan of rural and urban burrowing owls

This study tested whether fear of humans (measured as flight initiation distance in a diurnal owl) is reduced through habituation to human presence (plasticity) or whether it remains unchanged throughout the individuals' life, and results show an unusually high level of individual consistency in fear of Humans.

Urban mockingbirds quickly learn to identify individual humans

The varying responses of mockingbirds to intruders suggests behavioral flexibility and a keen awareness of different levels of threat posed by individuals of another species: traits that may predispose mockingbirds and other species of urban wildlife to successful exploitation of human-dominated environments.

Animal behavior in urban ecosystems: Modifications due to human-induced stress

Wildlife-human interactions are increasing in prevalence as urban sprawl continues to encroach into rural areas. Once considered to be unsuitable habitat for most wildlife species, urban/suburban

Pedestrian Density Influences Flight Distances of Urban Birds

This study provides empirical documentation of changes in anti-predator behaviour, which strongly correlate with the pedestrian density gradient and could support the idea that the establishment of FID can be highly plastic process depending on local conditions, as it is highly affected by a bird's individuality and its ability to adapt to the local level of disturbance by learning.

Disturbances by dog barking increase vigilance in coots Fulica atra

It is found that coots respond to acoustic traits of dogs and may be able to acoustically recognise this predator and this increase in vigilance might have implications for conservation, especially when considering buffer zones around sensitive areas.

Flight distances of black-billed magpies in different regimes of human density and persecution

Vertebrate responses to human beings have both a learned and genetic component. The learned component is apparently influenced by both the number and outcome of individual human-bird interactions

Increased tolerance to humans among disturbed wildlife

It is found that, overall, disturbed populations of the three major taxa are more tolerant of human disturbance than less disturbed populations and the best predictors of the direction and magnitude of bird tolerance are the type of disturbed area and body mass.

Four-legged friend or foe? Dog walking displaces native birds from natural areas

It is shown that dog walking in woodland leads to a 35% reduction in bird diversity and 41% reductionIn abundance, both in areas where dog walking is common and where dogs are prohibited, which argues against access by dog walkers to sensitive conservation areas.

Flight distance of urban birds, predation, and selection for urban life

Testing the hypothesis that the decrease in flight distance to a potential predator reflected adaptation to urbanization found species that had adapted to urban environments as shown by short flight distances were less susceptible to predation by the European sparrowhawk Accipiter nisus.
