Average UV blue crown spectra for male (blue) and female (orange) blue tits sampled in 2011 (a) in Corsica and (b) on the mainland. Average yellow chest spectra for male (black) and female (red) blue tits sampled in 2011 (c) in Corsica and (d) on the mainland. Thick lines represent mean spectra and shaded areas associated s.d. values. Plots were realized using the R package ‘pavo’ (www.rafaelmaia.net/r-packages/pavo).
