Figure S1. Phylogenetic tree for the nineteen bird species included in this study and their flight distance category.
Figure S2.The period over which wing moult data was recorded for each species.The boxplots display the minimum, 1stand 3rdquartiles, median and maximum values of each species.
Table S1. Species categorization according to three flight distance classes: A: 1 - 25 m, B: 25 - 200 m, and C: 200 m, by fifteen experienced birdwatchers (depicted by their initials). Total counts for each flight class are given at the bottom, with total of the selected category in bold.
