Effect of food predictability on the energy budget of wintering great tits (Parus major) in southern Sweden
Birds living in temperate regions face an energetically demanding period in winter, when food availability becomes reduced and unpredictable. In order to conserve energy, wintering passerines reduce their metabolic rate (MR) and body temperature (Tb) during the night to enter into a state of hypothermia. The effect of food predictability on the energy budget of birds is not fully understood. There
