Winter creates significant welfare challenges for wild animals through food scarcity, thermoregulation costs, and predation vulnerability — with implications for welfare science.
Winter welfare in wild animals illustrates the chronic suffering dimension of wild animal life that welfare science increasingly engages. Food scarcity, thermoregulation energy costs, and predation vulnerability during winter months create conditions in which large proportions of populations die from hunger, cold, and exhaustion. The welfare experience of animals experiencing slow starvation in winter — as documented in behavioral and physiological research on deer, birds, and small mammals — involves genuine suffering. Whether and how humans should intervene in wild animal winter suffering is one of the central debates in wild animal welfare, balancing welfare concern against ecological integrity.
