Colouration of spotless starling nestlings shows genetic and environmentally determined characteristics while begging for food [Dataset]

Abstract

Data file includes information about identity of each sampled starling nestling, the experiment and treatment assigned to them, biometric measurements on day 10 and day 14, and measurements of colour variables. Colour variables include colouration of eggshells (measured as Brightness and Blue-green chroma for eggs laid on the nest where each nestling was born (nest of origin), and the eggs laid on the nest where each nestling grew (nest of rearing)), and colouration of begging related traits (measured as Mean bright, Total hue, UV hue, Yellow-red hue, UV croma, Yellow-red chroma and Carotenoid chroma) for each body part (mouth, flanges and skin). The data set also includes the plasma carotenoid concentration of each sampled nestling.
