Abstract excerpt

The possession of a rhythm is usually described as an important adaptation to regular changing environmental conditions such as the light-dark cycle. However, recent studies have suggested plasticity in the expression of a rhythm depending on life history and environmental factors. Barn owl ( Tyto alba) nestlings show variations in behavior and physiology in relation to the size of black feather spots, a trait...
