In cold weather, what does a red-tailed hawk require more of?

In cold weather, a red-tailed hawk requires more food primarily because its energy expenditure increases significantly to maintain body temperature and cope with the thermal challenges of the environment. When temperatures drop, these birds must use more energy to stay warm, which necessitates an increase in caloric intake. They rely on the energy obtained from their prey to fuel their metabolism, especially in harsh conditions where hunting may be more demanding.

While hydration, rest, and proper training are important for a hawk's overall well-being, the immediate priority during cold weather revolves around ensuring that they have adequate food to sustain their energy levels and survive in lower temperatures.
