Randomized trial investigates genetic and environmental effects on coloration in great tits, suggesting implications for urban evolution.

This research aims to identify the genetic and environmental factors influencing coloration differences in urban versus forest great tits.
Examined color differences in urban and forest great tits.
Conducted a common garden experiment from unincubated egg stage.
Compared coloration traits, focusing on melanin patches and carotenoid saturation.
Urban males displayed smaller black ties compared to forest males (p<0.05).
Urban-origin common garden birds had reduced chromatic yellow breast and smaller ties (p<0.01).
No differences in yellow brightness or ultraviolet chroma between habitats in the common garden.

Sandmeyer et al. (2026) studied this question.
