Provisioning of food to wild birds is widespread but its ecological impacts are poorly understood. The authors show that winter provisioning with fat results in smaller relative yolk mass and reduced yolk carotenoid concentrations in early breeders, while these effects are not seen in birds provisioned with fat-plus-vitamin E. The results highlight how the ecological impacts of provisioning can depend on the nutritional profile of foods.
