Animal tolerance to human approaches may be used to establish buffers for wildlife that can minimize the probability that animals will be disturbed by human activity. Alert distance (the distance between an animal and an approaching human at which point the animal begins to exhibit alert behaviours to the human) has been proposed as an indicator of tolerance mainly for waterbirds; however, little is known about its utility for other bird species. The factors that influenced alert distances of… 
Human disturbance of breeding Wood Sandpipers Tringa glareola : implications for “ alert distances ” in prescribing protective buffer zones
TLDR
Three possible solutions to the dilemma of breeding Wood Sandpipers, in which Alert Distance could not be measured directly, are tested and the “fixed-slope rule” was supported, suggesting that this rule may have general utility in predicting Alert Distance when only the more readily measured Flight Initiation Distance metric is known.
Urban parks as shared spaces? The utility of alert distances as indicators of avian tolerance of humans in Stirling, Scotland
Urban avian foraging is strongly affected by approaching people. Avian alert distances, the instant of a bird’s appraisal of human intrusion, have not been studied in a comparative mode for
Managing human disturbance: factors influencing flight-initiation distance of birds in a West African nature reserve
Escape behaviour in response to perceived predators can be employed as a guide when designating protected areas around sensitive bird species to minimise the impact of human disturbance. A key
Database of Bird Flight Initiation Distances to Assist in Estimating Effects from Human Disturbance and Delineating Buffer Areas
Abstract U.S. Fish and Wildlife Service biologists determine effects from disturbance to threatened and endangered bird species, and staffs of federal and state agencies estimate these effects when
Bird flight initiation distances in relation to distance from human settlements in a Tanzanian floodplain habitat
AbstractHuman activity affects wildlife in many ways, but there have been few studies of how wildlife behavioural responses to human disturbance vary with distance from centres of human activity.
Escape distances from human pedestrians by staging waterbirds in a Danish wetland
TLDR
To aid planning of public access routes and the zoning of recreational activity in a Danish restored wetland, variation in the reactions of staging waterbirds to human activity were explored, using escape distances as an index of sensitivity to pedestrians.

The effects of human disturbance in urban parks of Madrid (Spain) on bird tolerance were studied to derive recommendations for urban park planning. We intended to determine (1) how habitat structure

Set‐Back Distances to Protect Nesting Bird Colonies from Human Disturbance in Florida
TLDR
A recommended set-back distance of about 100 meters for wading bird colonies and 180 meters for mixed tern/skimmer colonies should be adequate to effectively buffer the sites studied from human disturbance caused by approach of pedestrians and motor boats.
Behavioural and distributional effects of hunting disturbance on waterbirds in Europe : implications for refuge design
TLDR
Based on studies of effects of hunting disturbance on local waterbird distribution and abundance, freedom from such disturbance is concluded to be an important part of waterbird management on nature conservation areas and local site management planning should be integrated internationally.
RESPONSES OF WINTERING GRASSLAND RAPTORS TO HUMAN DISTURBANCE
TLDR
The objectives were to compare species- specific responses to the 2 disturbance types, to examine the hypothesis that flush distances positively correlate with species' body size (Cooke 1980), and to calculate minimum distances for species-specific buffer zones.

TLDR
Examination of inacanus dynamics of eagles, crows, and gulls scavenging on spawned salmon in the Pacific Northwest reveals that guild theory lends important insights to the understanding of the effects of human disturbance on wildlife communities.
A Method to Quantify the Effects of Human Disturbance on Animal Populations
TLDR
This study describes a method of quantifying the effect of disturbance based on measuring the trade-off between resource use and risk of disturbance, based on one used by ethologists to study the effects of predation risk on patch use.

TLDR
The short-term behavioral responses to visitors may reduce the suitability of highly disturbed parks in such a way as to decrease breeding densities and the probabilities of fragment occupation and persistence.
