Method synopsis

Field measurement of the distance at which birds first orientate to an approaching threat, used as a proxy for detection distance across multiple species and geographic regions.

Synthesized from method descriptions across 1 paper using this protocol.

Procedure from a recent peer-reviewed implementation

Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — Inter-specific variation in avian responses to human disturbance (2005), Journal of Applied Ecology. Implementations in other papers (listed below) may differ.

1. Alert distance data compilation
   Selected 150 species representing 107 genera and 40 families with at least 10 observations each. Calculated species' mean alert distance. Maximum body mass tabulated from Dunning (1993) or obtained from species accounts in Birds of North America and Handbook of Australian, New Zealand and Antarctic Birds. All variables log₁₀-transformed for analysis.
   Quantities: 150 species, 107 genera, 40 families, minimum 10 observations per speciesDuration: Data compilation from multiple published sourcesConditions: Field data collected by various researchers under natural conditions
   Equipment: Published literature sources, Species databases
