FID Records.xlsx

This dataset contains raw observational data collected for a study on flight initiation distance (FID) in blackbirds (Turdus merula). FID is the distance at which a bird initiates escape in response to an approaching human, and is commonly used as a measure of anti-predator behaviour.
Dataset Overview:Each row represents a single FID trial conducted under varying environmental and behavioural conditions. The columns include:
FID (m): Flight initiation distance in metersStarting Distance (m): Distance between the observer and bird when the approach beganHabitat Type: Urban or rural classificationSeason: Season during which the observation occurredTrial Order: Order of trials for each individual (where applicable)Individual ID: Unique identifier for birds (if relighted)Weather Conditions: Basic weather info (e.g., sunny, cloudy, windy)Initial Behaviour: Bird’s behaviour before the approach (e.g., foraging, perched)Other variables (if applicable): e.g., distance to cover, flock size, observer ID, etc.Notes:All measurements are in metric units.Values were recorded under standardized protocols to minimize observer bias.
