This dataset contains raw observational data collected for a study on <b>flight initiation distance (FID)</b> in blackbirds (<i>Turdus merula</i>). 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 behavior.Dataset Overview:Each row represents a single FID trial conducted under varying environmental and behavioral conditions. The columns include:<b>FID (m):</b> Flight initiation distance in meters<b>Starting Distance (m):</b> Distance between the observer and bird when the approach began<b>Habitat Type:</b> Urban or rural classification<b>Season:</b> Season during which the observation occurred<b>Trial Order:</b> Order of trials for each individual (where applicable)<b>Individual ID:</b> Unique identifier for birds (if resighted)<b>Weather Conditions:</b> Basic weather info (e.g., sunny, cloudy, windy)<b>Initial Behavior:</b> Bird’s behavior before the approach (e.g., foraging, perched)<b>Other variables (if applicable):</b> e.g., distance to cover, flock size, observer ID, etc. NotesAll measurements are in metric units.Values were recorded under standardized protocols to minimize observer bias.<br><b>Title:</b> R Script for Analysis of Flight Initiation Distance in Blackbirds<br><b>Description:</b><br>This R script (<code>FID_analysis.R</code>) contains the full statistical analysis used in the study on flight initiation distance (FID) in blackbirds (<i>Turdus merula</i>). It includes data cleaning, exploratory analysis, generalized linear or mixed-effects modeling, and visualization. The code is fully annotated and designed for reproducibility. It accompanies the dataset available in the same repository and supports all results reported in the associated manuscript.<br><br>
